Re: [Xsltforms-support] Can you use the date picker without setting the type to xs:date?

[Leigh L K. Jr <lei...@xe...>]

There is a way to express this in XForms 1.1:

Use the date type in the XForms namespace, which is defined as union of 
empty and xsd:date.
Processors should give you this effect when you use the unqualified names:

<bind nodeset="foo" type="date" />

See http://www.w3.org/TR/xforms11/#empty-content-types

In an XForms 1.0 processor, you can do the same thing by defining your 
own type to be a union of xsd:date and the empty string.
