Alex,
Thanks so much for the multiple responses to my questions so far.
You have been VERY helpful in my efforts. I have another question
regarding the use of the regular expression in the constraint. It may not
have much to do with XForms or the presentation server but I'm not sure
how to get around it. Using my previous example
<xforms:bind nodeset="/form/user/email" constraint=". =
'A-Za-z0-9!#-'\*\+\-/=\?\^_`\{-~]+(\.[A-Za-z0-9!#-'\*\+\-/=\?\^_`\{-~]+)*@
[A-Za-z0-9!#-'\*\+\-/=\?\^_`\{-~]+(\.[A-Za-z0-9!#-'\*\+\-/=\?\^_`\{-~]+)*'
"/>
Would in theory become
<xforms:bind nodeset="/form/user/email" constraint=" matches(. ,
"'A-Za-z0-9!#-'\*\+\-/=\?\^_`\{-~]+(\.[A-Za-z0-9!#-'\*\+\-/=\?\^_`\{-~]+)*
@
[A-Za-z0-9!#-'\*\+\-/=\?\^_`\{-~]+(\.[A-Za-z0-9!#-'\*\+\-/=\?\^_`\{-~]+)*'
") "/>
The problem is the quotes ("). The regular expression contains single
quotes (') and the constraint is enclosed in double quotes (") so using
either one to enclose the regular expression is 'problematic' at best.
Any ideas how I would get around this?
Very Respectfully,
Gregory J Blajian

In the "constraint" expression you can use the matches() function to check
against a regular expression. For more on matches() see:

Then using the matches() function in a <xforms:bind constraint="..."/>
should do it.

The summary page just lists the documents. The XForms validation with a
schema is done on the detail page in detail/detail-xforms-model.xml.
You will notice there the schema="form-schema.xsd" on the root element.
With this, the instance will be validated against the schema, and invalid
nodes will be marked with xxforms:valid="false" as usual.
From the perspective of the view or the page flow, it doesn't matter if
validation is done with a schema or with XForms model item properties.
