Yes, but PI targets starting by "xml" happen to be reserved for use by 
the W3C ;=) ...

More seriously, this would be quite useful (even though by analogy with 
xml:space, this could also be represented by an xml:ns attribute) but 
this is quite different from what I had in mind.

<?sanity type="normal|sane|neurotic|psychotic"?> would not be so much an 
instruction about how namespace prefixes can be rewriten or not but 
rather an instruction allowing to switch to a simpler processing model 
for parsers and applications.

This could lead to application profiles and could also be:

<?profile type="common|full"?>

or whatever variation on this theme where "common".

Yes, I think that the two issues are related but independent!
