No, I didn't say that.  I noted that the xmlns* attributes were
already handled by the XML Namespaces specification processingin
case you then replied that I had forgotten them.

No, XML Base describes how the attribute values deliver base URIs, it
does not require or forbid removal.

I will add case-independent to the editorial clarification of 6.1.2
for attribute names.

As for element names starting with these letters, I will ask the RDF
Core working group if it wants to do something about them such
as ignoring them, after the existing decision to ignore the
unrecognised attributes recorded in item 12
  http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2002Jan/0152.html

I doubt very much if you will find many other specifications based on
XML that bother to re-iterate this XML detail again.  They assume you
follow the normative references to the XML specifications and know
that they reserve some names.  I'm pretty sure they don't tell you
what to do with known or unknown xml* names in their documents.
