To add to my previous response, if you aren't using schema-aware processing,
then in 2.0 you can test

if test="$x castable as xs:integer"

Note the distinction: we're not testing whether $x *is* an integer, we're
testing whether it can be converted to an integer.

In 1.0 there's no such thing as an integer, but you can test whether a value
is numeric using

string(number($x)) = 'NaN'

and you can test whether it's a whole number using

number($x) = round(number($x))

or if you prefer (this one disallows 3.0)

not(contains($x, '.'))
