Subject: XSLT 2.0 and external parameters: a string -> xsd:integer. How?

I guess this is another angle on the typing questions that have been floating around the list recently.

Code that worked with Saxon 7.4 (and that I think would work in XSLT 1.0) is now broken with Saxon 7.5.

How can I supply an external parameter to a Saxon 7.5 stylesheet which is $number and has an integer value and get the XSLT processor to treat it as an xsd:integer. Well, I don't particularly want the parameter to be xsd:integer but I assume I won't be able to do anything numeric with it, unless I make it explicitly numeric.

If I try to ignore types altogether Saxon 7.5 complains, not surprisingly, that it cannot compare xsd:string to xsd:integer. If there is a way to write a type-agnostic stylesheet to accept a parameter that is intended to be numeric it isn't obvious to me at the moment.

So I made the input parameter xsd:string and created a new numeric parameter using the xsd:integer() constructor function. Same error message.

Then I tried making the input parameter xdt:untypedAtomic with the xsd:integer() constructor function to create the second parameter. Same error message.

Then I tried adding an as="xsd:integer". Same error message.

The Saxon 7.5 documentation indicates that "most" such functions are supported. Is this one unsupported or am I missing a basic trick somewhere?

I want to input a parameter at the command line, .... number=3 (which is presumably a string at the point where it is bound to a global parameter (which I have called $string), and later use that value (with $number constructed using xsd:integer($string) ) as an xsd:integer.

How can that be done?

Thanks
