1. If an xml attribute is defined as Type="xs:QName", then do XML parsers like SAX and DOM do the resolution of those names? Example: Assume AttributeDesignatorType is defined as follows: <xs:complexType name="AttributeDesignatorType"> <xs:attribute name="AttributeId" type="xs:QName" use="required"/> <xs:attribute name="DataType" type="xs:anyURI" use="required"/> <xs:attribute name="Issuer" type="xs:anyURI" use="optional"/> </xs:complexType> Then, if my Policy says <Policy xmlns="urn:oasis:names:tc:xacml:1.0:policy" xmlns:sun-attrs="urn:sun:names:attribute-ids" ... <SubjectAttributeDesignator AttributeId="sun-attrs:attr1" .../> And a Request says <Request xmlns="urn:oasis:names:tc:xacml:1.0:context" xmlns:sun-stuff="urn:sun:names:attribute-ids" ... <Subject> <Attribute AttributeId="sun-stuff:attr1"> ... Will the tools themselves resolve these, or do I have to expand the names and then perform a string match myself? 2. Does anyone have a reference from W3C on whether QNames MAY be used as "aliases" for any URI or whether they are ONLY for use in referring to URI's that represent schemas? I.e. are the uses of QNames for use in identifiers as in #1 and in our current schemas even allowed (or recommended)? 3. Is there a way to define aliases for shortcut names other than QNames? I.e. can I define an alias to be equal to some initial prefix of a long URI, and then have that expanded by XML parsing tools? Anne -- Anne H.
