Subject:  XSLT 2.0/XPath 2.0 Date arithmetic

Given a parameter, let's call it "today" in the form of this string
"20060517", how do I create a variable, let's call it "tMinus1" such
that it represents a day earlier than "20060517", that would be
"20060516". So long as "$today" isn't the first day of a month, a simple
subtraction and followed by a type cast that I don't grasp would do the
trick.

What I'm looking for is guidance on date arithmetic.

Thanks.
