RE: PIDF - using xml schema

I've just finished reading draft-hollenbeck-ietf-xml-guidelines-00.txt
and have the following observations for consideration:

* draft-ietf-impp-cpim-pidf-02.txt:Section 3.1

I think we should change this to REQUIRE an XML declaration. We should
mandate the use of UTF-8 and recommend that the encoding attribute
SHOULD be used to explicitly note the use of UTF-8.

We should also require that documents MUST be well-formed.


* draft-ietf-impp-cpim-pidf-02.txt:Section 4.1.7

I think we should mandate the use of the xml:lang attribute for the
<note> element. Should it be possible to have more than one <note>
element for different languages?


* draft-ietf-impp-cpim-pidf-02.txt:Section 4.4

Rather than the DTD, we should use an XML schema and insist that PIDF
documents MUST be valid according to the schema.

I had a quick look - at first glance the only thing that flagged up was
using xs:dateTime for the timestamp. I'm not sure how this compares to
the IMPP datetime format that we mandate.
