Re: Normalizing string containing entities

entities are no problem as they are all expanded before XSL sees the
document.

normalising space in mixed content is _always_ a problem.
Of course normally you just don't do it, as the renderer (eg html in
this case) can more easily do it as it lays out the characters, after
all the markup is gone.

If you do want to do it within the markup, the problem as stated was
underspecified, but here is a possible (probably partial) solution.
As always documented to the "literate programming" standards discussed
in an earlier thread on this list.
