XFA ( also known as XFA forms ) stands for XML Forms Architecture, a family of proprietary XML specifications that was suggested and developed by JetForm to enhance the processing of web forms.

According to JetForm's submission to the World Wide Web Consortium, " XFA addresses the needs of organizations to securely capture, present, move, process, output and print information associated with electronic forms.

In 2002, the JetForm Corporation was acquired by Adobe Systems, and the latter introduced XFA forms with PDF 1. 5 and the subsequent Acrobat releases ( 6 and 7 ) in 2003.

XFA forms are synonymous with SmartForms in the Australian government.

* Adobe XML Forms Architecture ( XFA ) forms, introduced in the PDF 1. 5 format specification as an optional feature ( The XFA specification is not included in the PDF specification, it is only referenced.

XFA forms can be created and used as PDF files or as XDP ( XML Data Package ).

Adobe XFA Forms are not compatible with AcroForms.

The XFA Forms are not compatible with Adobe Reader prior to version 6.

When the PDF and XFA are combined, the result is a form in which each page of the XFA form overlays a PDF background.

When the XFA ( XML Forms Architecture ) grammars used for an XFA form are moved from one application to another, they must be packaged as an XML Data Package.

Adobe Reader contains " disabled features " for use of XFA Forms, that will activate only when opening a PDF document that was created using enabling technology available only from Adobe.

The format of an XFA resource in PDF is described by the XML Data Package Specification.

PDF may contain XFA in XDP format, but also XFA may contain PDF.

The alternative is to express all of the form, including boilerplate, directly in XFA ( without PDF ).

In PDF 1. 6, PDF supports the rich text elements and attributes specified in the XML Forms Architecture ( XFA ) Specification, 2. 2.

In PDF 1. 7, PDF supports the rich text elements and attributes specified in the XML Forms Architecture ( XFA ) Specification, 2. 4.

PDF 2. 0 ( ISO 32000 Part 2 ) will reference XFA 3. 1.

In 2011 the ISO Committee urged Adobe Systems to submit the XFA Specification, XML Forms Architecture ( XFA ), to ISO for standardization and requested Adobe Systems to stabilize the XFA specification.

* Adobe XML Forms Architecture ( XFA )-developer resources

Creating XFA Forms for use in Adobe Reader requires Adobe LiveCycle Forms Designer.

* General Aviation XFA, an experimental aircraft of the U. S. Army

In addition, all instances created from a given XFA form template keep the specification of data capture, rendering, and manipulation rules from the original.

Another major advantage of XFA is that its data format allows compatibility with other systems, and with changes to other technology, applications and technology standards.

" The XFA proposal was submitted to the W3C in May 1999.

I have chosen to use the word `` mimesis '' in its Christian rather than its classic implications and to discover in the concrete forms of both art and myth powers of theological expression which, as in the Christian mind, are the direct consequence of involvement in historical experience, which are not reserved, as in the Greek mind, only to moments of theoretical reflection.

The pamphlets are about law, the corporation, forms of government, the idea of freedom, the defense of liberty, the various lethargies which overtake our major institutions, the gap between traditional social ideals and the working mechanisms that have been set in motion for their realization.

When combined with the metaphysical notion that pure forms of this universe are best appreciated when least embodied in a material substratum, it becomes clear that while earth will be dross on a scale of material-formal ratios, celestial bodies will be of a subtle, quickened, ethereal existence, in whose embodiment pure form will be the dominant component and matter will be absent or remain subsidiary.

This understanding, of course, may in its turn take many forms and some of these -- especially those most interesting to the student of comparative literature -- are essentially historical.

Once the poetic arts are separated from the other forms, he lays down his famous definition of tragedy, which sets up standards and so lends direction to the remainder of the work.

Even in the nineteenth century such accomplished philologists as Kemble and Guest were led into what now seem ludicrous errors because of their failure to recognize that modern forms of place names are not necessarily the result of logical philological development.

in working with these patients the therapist eventually gets to do some at least private mulling over of the possible meaning of a belch, or the passage of flatus, not only because he is reduced to this for lack of anything else to analyze, but also because he learns that even these animal-like sounds constitute forms of communication in which, from time to time, quite different things are being said, long before the patient can become sufficiently aware of these, as distinct feelings and concepts, to say them in words.

Dictionary forms found to match forms in the text list are marked.

The dictionary is a form dictionary, at least in the sense that complete forms are used as the basis for matching text occurrences with dictionary entries.

For this step the computer memory is separated into three regions: cells in the W-region are used for storage of the forms in the text-form list ; ;

cells in the X-region and Y region are reserved as information cells for text forms.

The list of text forms in the W-region of memory and the contents of the information cells in the X and Y-regions are no longer required.

The grammatical descriptions of all forms in the dictionary are recorded in a separate part of the dictionary file.

The only requirements on dictionary information made by the text-lookup operation are that each form represented by the dictionary be available for lookup in the text-form list and that information for each form be available in a sequence identical with the sequence of the forms.

Two very useful ways for modifying a form-dictionary are the addition to the dictionary of complete paradigms rather than single forms and the application of a single change to more than one dictionary form.

If all forms of a paradigm are grouped together within the dictionary, a considerable reduction in the amount of information required is possible.

There would be no conceivable sense in going to the opposite extreme of selecting items whose forms are the most unstable.

The rows of animals and birds, in particular, suggest awareness of Oriental animal friezes, transmitted perhaps via Syrian silver bowls and textiles, but the specific forms of these rows on local vases and metal products are nonetheless Greek.

While patent suits are still among the most complex and expensive forms of litigation, these rules have saved litigants uncounted sums of money.

But since this is a world in which people disagree about ends and goals and concerning justice and injustice, and since, in a situation where direct action and economic pressure are called for, the justice of the matter has either not been clearly defined by law or the law is not effectively present, there has to be a morality of means applied in every case in which people take it upon themselves to use economic pressures or other forms of force.

Nor is it necessary to look for such evidence in the great urban centers of our culture that are admittedly almost entirely secularized and so profoundly estranged from the conventional forms in which the gospel has been communicated.

Although the theological forms of the past continue to exist in a way they do not in a more secularized situation, the striking thing is the rapidity with which they are being reduced to a marginal existence.

In the absence of a truly adequate conceptuality in which the gospel can be expressed, the unavoidable need to demythologize it makes use of whatever resources are at hand -- and this usually means one or another of the various forms of `` folk religion '' current in the situation.
