Some more review of the XPath Expression Module

All,

I have reviewed the module up to, but not including, section 4.3
"String Functions".

I made a couple of trivial edits here:

    https://www.w3.org/MarkUp/Forms/wiki/index.php?title=XPath_Expressions_Module&diff=4192&oldid=4190

We already discussed the min/max functions and I have the following
action items related to functions:

- ACTION-2022 - Write text for min/max in compatibility mode
- ACTION-2023: Check compatibility problems with seconds-from-datetime
and one other

I think that we also discussed issues with the signature of the
power() function, which Steven will take care of.

In addition to the above, I see issues with the following functions:

- avg(), which should take and return values of the same type, like min/max
- index(), which says it returns an xs:integer, but then says it can return NaN
- random(), which should probably just return xs:double

To discuss during the next call.

-Erik
