RE: validating an xform

Laszlo,

XForms 1.1 declares a set of additional datatypes that correspond to many of the XML Schema Datatypes, only they allow empty values[0].  Your example might look like the following, when using one of these XForms datatypes:

  <xforms:bind nodeset="/data/number" type="xforms:integer"/>

Of course, your processor will need to support them for this to help you.  Based on the implementation report[1], it looks like the Mozilla XForms Extension supports this datatype, but I haven't tested that myself.

Take care,

    John L. Clark

Thanks for the answers. I have a difficulty with types. I have an
input form, where I'd like to accept integers only. The field is
optional. However, if I precise its type to be "xsd:integer", the
field becomes required since an empty field is not an integer. So the
field must be filled otherwise the form cannot be sent :( Here is what
I tried:

<xforms:bind nodeset="/data/number" type="xsd:integer" required="false()" />

However, required="false()" has no effect. How to set it optional?

Thanks,

Laszlo
