Re:  Long Namespaces
I would rather have longer and more descripitve element and attributes
then namespace prefixes.....saves on keystrokes having something
shorter and you will reduce verbosity of a document if you avoid
longer then 3-4 character namespace prefixes.

As Joe said, it doesn't matter as these prefixes only have relevance
in that particular document...that being said, people tend to use the
same prefix.

If you have a deep inheritence hierarchy you might find having a long
descriptive prefix in the master document useful......though even then
I would advise that this type of question is typically answered by how
you generate the XML in question (e.g. using an editor, manual, or is
it the output of some process).

Ok, so I messed up that post ; )
I meant to ask about verbose prefixes!  So an example:

xmlns:myVerbosePrefix = "http://mydomain.com/verboseprefixes"

Anyone going that route?  Reason I ask, is here at work, my colleagues
are not so familiar with XSLT.  They did not like 3 letter prefixes,
said it was confusing.
