So, though I do not need it anymore because I have the problem with multiple exclusions, the following should *not* have a particle ambiguity: <xs:complexType name="any-non-UBL"> <xs:choice minOccurs="0" maxOccurs="unbounded"> <xs:any namespace="##other" processContents="skip" minOccurs="0" maxOccurs="unbounded"/> <xs:any namespace="##local" processContents="skip" minOccurs="0" maxOccurs="unbounded"/> </xs:choice> </xs:complexType> And Xerces interprets this correctly. However, for UBL I have to use just: <xs:complexType name="extension"> <xs:sequence> <xs:any namespace="##other" processContents="skip" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> and make it a layered business rule that UBL-namespaced constructs (of the four namespaces) are not allowed as immediate children of the UBL extension point based on your earlier comment: At 2006-05-23 13:24 +0100, Michael Kay wrote: > > Now ... how best to enumerate a *list* of namespaces to be > > excluded from a content model? > >I'm pretty sure you can't do that. > >Hence the rule that if two attribute wildcards exclude different namespaces, >their intersection is "not expressible" (3.10.6) Third subsection, 5th bullet ... thanks, Mike.
