Hi John,

I do apologise...again. :)

I misread this:

  The function library for XPath expressions includes the entire
[XPath 1.0] Core
  Function Library, including operations on node-sets, strings, numbers, and
  booleans.

For some reason I interpreted it to mean that 'this library' included
the XPath core functions, alongside the additional functions that
'this library' defines.

But on re-reading I realise that this sentence is merely setting the
scene for the next sentences:

  The following sections define additional functions that are required
to implement
  by this module: 2.1 Boolean Functions, 2.2 Number Functions, 2.3
String Functions,
  2.4 Date and Time Functions, 2.5 Node-set Functions and 2.6 Object Functions.
  Other modules of the consuming profile may add more functions to the
function library.

I.e., 'XPath defines some core functions, and here we're extending them'.

Other than a minor typo ("required to implement by this module") I see
that everything is indeed how you say it is...so apologies again!

Regards,

Mark
