Yes, that is useful.  But airing an idea in front community of 
experienced craftsmen is not to be disparaged either, I trust.  Of 
course everybody is busy, and nobody is obliged to answer.

Yes.  I think we're in violent agreement.  I was making the same point 
to James Anderson.

I'm unsure what you're objecting to.  If you dislike the Qexo license, 
that is not a topic for this list, but that would only apply to an 
implementation of these ideas.  The idea itself, whatever its 
originality or merit, is available to all.

Of course you are busy and have no obligation to do so.  Though it would 
be nice to be spared the snide attitude.

I don't know what "output I myself predicted", but my algorithm would 
not produce the above example:

"When serializing an element, we print all the namespaces in the
element's namespace mapping, except for ones that are redundant because
they have already been serialized in an enclosing element."

I guess I must manage without your feedback.  Luckily, I have some 
experience as a language implementer myself.

Ok, you win when it comes to XML.

I won't bother listing my credentials.
