[Xsltforms-support] trouble with XML schema that specializes its own simpleType

[Adam M. <Ada...@gm...>]

Hi Alain & everyone,

I've found XSLTForms 576 does not appreciate an XML Schema that
specializes its own SimpleType.

For example, if my schema defines this simple type:

    <xs:simpleType name="nonEmptyString">
        <xs:restriction base="xs:string">
            <xs:minLength value="1"/>
            <xs:pattern value="\S+(.*\S+)?"/>
        </xs:restriction>
    </xs:simpleType>

... and then specializes it to create another simple type:

    <xs:simpleType name="string100">
        <xs:restriction base="myns:nonEmptyString">
            <xs:maxLength value="100"/>
        </xs:restriction>
    </xs:simpleType>

... then XSLTForms will not accept the schema.  It complains:

    "Schema for namespace undefined not defined for type nonEmptyString"

The schema is valid.  If I load it into <oXygen/> editor for example,
it correctly understands the "string100" type.

I can work around this by making the "string100" type a specialization
of "xs:string", and repeating in the "string100" type all the
constraints that are specified for the "nonEmptyString" type.

What do you make of this?

Thanks!
