I have seen this issue mentioned multiple times.  However it is my
understanding after reading many, many posts that this should work,
yet it is not working and I am looking for some help.

I am not looking to perform a date CALCULATION only a COMPARISON which
I understand to be possible using string-compare.  Here is the
situation and sample xpath statement

1.  I am populating a listbox with dates from a sharepoint calendar
list, these dates come in as the @Begin field and always include date
and Time

2.  I want to filter this field so only events in the future show up.
Therefore I need to compare the sharepoint @Begin with today() and
filter for those entries in which @Begin > Today()

3.  I am attempting to use the following filter on the field with
absolutely no success.  The use of substring is used in order to
truncate the date/time sharepoint sends into an 11 character date that
parallells the ISO type that Infopath uses.  I have tested the
substring in a separate field and get YYYY-MM-DD just as I expected.

msxsl:string-compare(substring(., 0, 11), string(xdDate:Today())) > 0

In fact this produces some odd results I can't explain.  This filters
out all dates that are After today, however reversing the formula or
adding a not() does not return the results I am looking for.

Please help if you can
