Why should it be bad? I don't see why it should be forbidden neither do 
I see where it should cause harm.

You should just keep in mind, that

<message xmlns='jabber:client' to='...' from='...'>...
and
<foo:message xmlns='jabber:client' to='...' from='...'>...

are from the pure XML point of view the same as a 'normal' stanza 
without the xmlns attribute,

while

<message xmlns:foo='jabber:client' foo:to='...' foo:from='...'>...
and
<foo:message xmlns:foo='jabber:client' foo:to='...' foo:from='...'>...

are not equivalent to the above to stanzas. I.e. an attribute name 
without a prefix does not denote an attribute in the default namespace, 
but an attribute that belongs to the element.
