Thanks David.  Okay, then here's a real brain teaser:

In the XML Schema specification, Section F.1.1 Character Class Escapes, it
includes regular expressions for
\n the newline character line-feed (#xA), and \r the return character (#xD),
as well as the Unicode separator Category Escape (Z, Zs, Zl, Zp).

Why even have these if the end-of-line handling in XML 1.0 or 1.1 always
normalizes these to line-feed (#xA)?
