12.2.3 Conforming XForms Generators
The XForms specification is designed for implementation on hardware platforms of all sizes, from tiny handheld devices to high-powered servers. Clearly, a one-size-fits-all approach has its drawbacks. For this reason, there are two conformance levels for XForms Processors, documents, and authoring tools.
This conformance level will be suitable for devices with limited
computing power, such as mobile phones, handheld computers, and appliances.
This conformance level will depend on a subset of XML Schema, and will not
include any resource-intensive features. Implementations of XForms Basic should
basic" for the
Resource-limited XForms Processors may define implementation limits
on the maximum size of a
node-set returned by XPath expressions.
All XForms Processors must support the required portions of the specifications normatively listed as references (C References).
XForms Basic Processors must implement all required features labeled as Basic.
XForms Full Processors must implement all required features.
All XForms Containing Documents must conform to the required portions
of the specifications normatively listed as references (C References). XForms elements are typically inserted into a containing
document in multiple places. The root element for each individual fragment must
model, a form control, or one of
repeat. Individual XForms fragments must be schema-valid against the
Schema for XForms (A Schema for XForms).
All XForms Basic Containing Documents must conform to all required portions of this specification marked as Basic, and additionally not include any features not specifically marked as Basic.
All XForms Full Containing Documents must conform to all required portions of this specification.
