It would really be a nasty bug, in case Mukul got that output.

However, what he got (note the capitalisation) was:

<AUTHOR xmlns:auto-ns1="HTTP://WWW.W3.ORG/XML/1998/NAMESPACE"
xmlns:A="XYZ" xmlns:B="PQR">

Also in the code sample he provided there is no filtering of the "xml"
namespace.

Mukul's statement that:

But this predicate doesn't work as expected, with MSXML. MSXML outputs
xmlns:auto-ns1="http://www.w3.org/xml/1998/namespace" in the absence
of this predicate.

is both contradictory and untrue. Contradictory, because he says "this
predicate doesn't work as expected, with MSXML" and then makes it
clear what "didn't work" was produced "in the absence of this
predicate".

Untrue, because the real result is very different:

xmlns:auto-ns1="HTTP://WWW.W3.ORG/XML/1998/NAMESPACE"
