Re: number collapsing

Your function could (no, will) fail with a fatal type error if passed with first
arguent something that is castable to an intger but is not an intger or
automatically coerced to an integer.

so if the first argument is

1          you are OK (It's an intger)
"iii"      You are OK, it's not castable to an intger so your xsl:choose
           takes the right branch
"123"      You die as described previously, unless you modify as MK showed.
mods:start This is data from a source doc. If you are not using a schema
           then this is untyped data and most operations _do_
           automatically cast untyped data to the appropriate type
           so most likely you get away with it here.
           If you are using a schema aware processor and a schema and
           that schema says mods:start is anything other than an intger,
           you die.
