Re: XForms in HTML Example will not validate

Hi Robert,

The working group discussed the concern you raised today and has asked me 
to provide the following response:

XForms is designed to be a module that can be hosted by multiple host 
presentation languages (including multiple host languages being used 
simultaneously). XForms provides a rich array of XML data interaction and 
server connectivity capabilities to host languages. In an informative 
appendix (H), we provide an example using XHTML as the host language. 
Validation of XForms in combination with any host language requires a 
schema that combines XForms with that host language.  In the immediate 
term, you would need to do that in order for you to validate your 
documents. However, for greater convenience to the community in the 
future, the working group is taking action to define a working group note 
that specifically targets validation of XHTML with XForms, and the working 
group is also working on getting this profile added to the W3C validator.

XForms in HTML Example will not validate



Dear Editor,
I tried to make The example in Section H (
http://www.w3.org/TR/2009/REC-xforms-20091020/#xforms-in-xhtml-00) and the 
downloadable example (attached) work with both XMLSpy and OxYgen. OxYgen 
employs a special declaration for XForms that includes Relax NG code. 
<?oxygen NVDLSchema="xhtml-xforms.nvdl"?>. This does not appear to be 
portable. In short,  I would like to be able to use my CytometryML schemas 
with XForms including being able to have type checking active. Since the 
CytometryML schemas are proposed to be part of a standard, these schemas 
will be available without charge.  I believe that the  link to the XForms 
1.1, W3C Recommendation 20 October 2009 should provide a complete working 
example. I have attached the XForm and schema that I copied from the 
Recommendation. I also tested the XForm with the <?xml version="1.0" 
encoding="UTF-8"?> declaration removed. It produced similar errors.  Since 
html does not include XForms, the errors appear to be correct.  I have 
tested some approaches that appear to interfere with html’s schema 
validating elements from other namespaces. However, they did not work 
either.
 
Thank you.
