XML processor profiles: XML Base processing

Dear XML Processing Model Working Group,

  In http://www.w3.org/TR/2010/WD-xml-proc-profiles-20100518/ section 3
there is a requirement "Maintenance of the base URI property of each
element in conformance with [XML Base]". This requirement needs to be
elaborated in at least two ways. Firstly, it needs to be identified
whose property the "base URI" property is; secondly, it is difficult to
see what effect the requirement has beyond affecting XInclude processing
for which the requirement is already implied.

As per the XML Base specification, "The behavior of xml:base attributes
in applications based on specifications that do not have direct or
indirect normative reference to XML Base is undefined." and I am not
sure what I would need to read in the XML Base specification that I
would not already know from reading the URI, XML, etc. specifications.
Also, if the "base URI property" is the XML Information Set's property
of the same name, then that specification already has "Several
information items have a [base URI] or [declaration base URI] property.
These are computed according to [XML Base]."

Please either remove the XML Base requirement as redundant, or explain
the significance of the requirement better in the document.

regards,
