Errr, I think you are misunderstanding contains (possibly because of
how translate works).  If you read the function description for XPath
2.0 (or XPath 1.0, I don't think it has changed at all) it says the
function contains tests to see if the first string contains the second
string anywhere.  Unless $cont is always a single character or
contains a string in alphabetical order (like bc or CD), it's highly
unlikely it will match.  1a will give a false, since the first string
does not contain the string 1a anywhere.  Are you looking for a
function that will always return true if any character is a alpha
character ?

See for a description of XPath
2 functions and for the description of
XPath 1 functions.
