you mean, I think, xs:integer(@number-att), which is indeed possible. It 
will fail with an error if the @number-att contains any [^0-9.+-] (with 
some exceptions). However, there are several ways to prevent this 
(unrecoverable) error to be raised:

(: number() never fails :)
xs:integer(number(@number-att))

(: more cleanly, gives you more control :)
if (@number-att castable as xs:integer) then xs:integer(@number-att) else 0


etc.
