Possible issue or editorial cleanup item - missing equality predicates,etc.

There are no equality predicates in section A.3.1 for the following
datatypes:

  
urn:oasis:names:tc:xacml:2.0:data-type:ipAddress

  
urn:oasis:names:tc:xacml:2.0:data-type:dnsName

  
urn:oasis:names:tc:xacml:3.0:data-type:xpathExpression

I don't know if this was intentional, but suspect it was just an
oversight as these 3 data types were added after XACML 1.1.

Also, it appears some or all of them may be missing from some functions:

  
intersection

  
at-least-one-member-of

  
union

  
subset

  
set-equal

Also, I am curious what, if any, association might or might not be
intended between the first two above and the Subject identifiers:

  
urn:oasis:names:tc:xacml:1.0:subject:authn-locality:ip-address

  
urn:oasis:names:tc:xacml:2.0:data-type:dnsName
