I need an XPath 1.0 expression that will test a node and return a
boolean if the node content is a 3 digit number (i.e., 100-999) and
false if it's anything else.

The catch is this expression won't
be in a transformation so I can't use variables or other additional
constructs. All I get is one expression. I've tried this

*[(string(number(.)) !='NaN')]

and obtained the number that I need. But I can't get any sort of compare to work that makes the number be more than 99 and less than 1,000.
