B  Oops, good point, I didn't
check the current draft and thought it
was already part of it; I was wrong.

B  I am not sure why you think it should be only for generating text.
Actually an interesting use case I've discussed with Eric van der
Vlist, if
the result of the expression is added to the output tree
(and not its atomized
text value), is to indent properly complex XPath
expressions.

B  Thanks to
the power of XPath 2.0 (and this is going to be even more
true with XPath
3.0), the XPath expressions used in xsl:sequence are
more and more complex,
and need more and more to be properly indented
and edited.B  Which does not
always fit properly being the value of an
attribute (especially if the
attribute goes true an XML parser at some
point, loosing newline
characters).B  Using curly braces will then be
an easy way to solve that
problem (a la XQuery).

B  Regards,
