The XForms Basic Profile describes a minimal level of XForms processing tailored to the needs of constrained devices and environments.
This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.
This document is a Candidate Recommendation of the World Wide Web Consortium. (For background on this work, please see the XForms Activity Statement.) This specification is considered stable by the XForms Working Group and is available for public review.
The XForms Basic conformance level was part of the XForms 1.0 Candidate Recommendation. As this profile did not meet the CR exit criteria due to lack of implementation, it now remains as a Candidate Recommendation standalone document. XForms 1.0, defining only the XForms Full conformance level, proceeded to W3C Recommendation.
Publication as a Candidate Recommendation does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
This Candidate Recommendation provides an opportunity to implement this XForms Basic Profile in constrained environments, and allows the XForms Working Group to collect test cases and information about implementations.
Please send review comments to www-forms-editor@w3.org. The archive for the list is accessible online. We expect that sufficient feedback to determine its future will have been received by 01 March 2004.
The XForms Working Group will advance the specification to Proposed Recommendation when the following exit criteria have been met:
Sufficient reports of implementation experience have been gathered to demonstrate that XForms Basic Processors based on the specification are implementable and have compatible behavior.
An implementation report showing that there is at least one fully conforming XForms Basic processor.
Formal responses to all comments received by the Working Group.
Any feedback on patterns of implementation and use of this specification would be very welcome.
Should this profile prove impossible or very difficult to implement, the necessary changes to make it implementable will be made. If this profile is possible to implement, the only changes which will be made to this specification are minor editorial changes and clarifications.
Patent disclosures relevant to this specification may be found on the XForms Working Group's public patent disclosure page. As of this publication, the XForms Working Group are not aware of any royalty-bearing patents they believe to be essential to XForms 1.0.
The W3C XForms Working Group has released a public test suite for XForms 1.0 Full and Basic along with an implementation report.
This document has been produced by the W3C XForms Working Group as part of the XForms Activity within the W3C Interaction Domain. The authors of this document are the XForms Working Group participants.

A variety of devices, with widely varying characteristics and capabilities, have the potential to support XForms [XForms 1.0]. XForms 1.0 defines a conformance profile called XForms Full, suitable for more powerful forms processing, and including processing from several other W3C specifications. This document defines a more limited conformance profile, called XForms Basic.
Note that XForms Basic is a conformance profile for XForms Processors only. A new conformance level is not defined or needed for XForms Documents or XForms Generators. There is only one class of XForms document, with more advanced XForms Processors providing an enhanced experience for end users, for example by providing additional client-side validations.
This document uses the following conventions for namespace prefixes. In practice, any prefix can be used.
http://www.w3.org/2001/XMLSchema

This document uses terms defined in [RFC 2119].
XForms Basic Profile implementations must return "basic" from
the property method [XForms 1.0]
called with the "conformance-level" parameter string.
XForms Basic conforming processors must meet the conformance requirements defined for XForms 1.0, with the following differences:
XForms Basic Profile processors may support only XML Events Basic [XML Events].
XForms Basic Profile processors may implement a subset of an XML
Schema processor [XML Schema part 1], [XML Schema part 2], requiring only what is
necessary to process the attribute xsi:type on instance data
for simpleTypes only and the type model item property for
simpleTypes only.
XForms Basic Profile processors may treat XML Schema datatypes other
than the following as xsd:string:
dateTime
time
date
gYearMonth
gYear
gMonthDay
gDay
gMonth
string
boolean
base64Binary
decimal
anyURI
integer
nonPositiveInteger
negativeInteger
long
