They don't help do they?

Take alpha U+0391.  The UCD says that is Lu so it matches \p(Lu) but that
just tells you it's a lower case letter, it doesn't tell you it's in the
block
      <block start="00370" end="003FF" name="Greek and Coptic"/>
does it? The code I pointed to in the message you replied to would take
an alpha, get its code point, and find the string "0039" as being the
first four digits of a five digit hex representation of the codepoint,
then find this block element in unicode.xml, and thus (for example) to
http://www.unicode.org/charts/PDF/U0370.pdf
which is the pdf file which has the alpha glyph example.

Actually regexp could help, you could take the block range information
and build a regexp that matches each block by generating teh required
charater range expressions, but I think it's more natural to do that as
an xpath query rather than forcing it through the regexp engine.
