id attributes proposal, take 2

Take 2 on id attributes proposal.

It looks simple enough but there are side 
effects...

xs:ID attribute is derived from NCName type, and as 
such does not allow ':' character.

This attribute type is xs:anyURI in xacml 1.0 and 
this change may break policies wich use

urn's for set-id's

 

PolicySet:

<xs:complexType 
name="PolicySetType">

....

<xs:attribute name="PolicySetId" type="xs:ID" 
use="required"/>

</xs:complexType>

 

Policy:

<xs:complexType 
name="PolicyType">

...

<xs:attribute name="PolicyId" type="xs:ID" 
use="required"/>

</xs:complexType>

 

Rule:

<xs:complexType name="RuleType">

...

<xs:attribute name="RuleId" type="xs:ID", 
use="required"/>
</xs:complexType>
