Some questions on XForms

I wasn't sure where to publish some comments on my first experiences
with XForms. However, as some already asked questions about it here, I
thought I could join.

After playing around with an example that used xsd:decimal I tried
altering it to xsd:language and see if that worked:

<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:xf="http://www.w3.org/2002/xforms"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<style type="text/css">
/* Yes, that is one ugly hack. */
@namespace xforms url("http://www.w3.org/2002/xforms");
xforms|*[invalid] input { background-color: red; }
</style>
<xf:model>
<xf:instance>
<test xmlns="">
<foo>en</foo>
</test>
</xf:instance>
<xf:bind nodeset="/test/foo" type="xsd:language"/>
</xf:model>
<xf:input ref="/test/foo"><xf:label>Test xsd:language
</xf:label></xf:input>
</html>

.... apparently, it did not. (Also, when you change xsd:language to
xsd:decimal in the above example it does not change to NaN or is that
the behavior it should have?) Is this because xsd:language and possibly
other types are not yet implemented?

I was also wondering if NaN is a valid xsd:decimal value or not. Since
from testing it I sometimes get it back with a red background and
sometimes not.

Mozilla doesn't support xsd:language at this time for Schema Validation.
It is not on the must have list XForms defines, so its low in priority.

http://w3.org/TR/xmlschema-2/#decimal makes no mention of NaN, so
probably not valid. I believe float and double do specify it, but I
know that Mozilla doesn't support NaN for those.

Ok.

So when you multiple to fields and have the result in a third field it
can not even be NaN? (We do that know.) It seems strange that all other
numeric types do define NaN and xsd:decimal does not... Perhaps an
oversight?

Well, float and double are hardley all other types ;)
