I would also prefer to make references. Both for 3.0 and the 2.0 errata.

BTW, I noticed that the copied text in the 2.0 errata (and the ITU-T
text I presume) uses different namespaces and identifiers than the text
which the XACML 2.0 OASIS standard refers to. This means that the ITU-T
version is not entirely interoperable with the OASIS version. For 3.0 I
suggest we stay backwards compatible with the OASIS version. (Which is
what is going to happen if we make a reference, rather than a copy.)

Regarding XACML 3.0 and ITU-T, I haven't even considered that yet. I'll
be happy enough with making it an OASIS standard first. :-)
