It's true that the availability of domain-specific libraries may influence
your choice of programming language. Sometimes this will steer you away from
XSLT, sometimes towards it. 

And XSLT is just as capable of making cross-language library calls as any
other programming language. Indeed, some people choose to write applications
in XSLT that do little else.

I suspect that your colleague might not be aware that there is a library
specifically for processing geographic information in XSLT:
https://sourceforge.net/projects/geofunctions 

It's true that XSLT is a specialized language rather than a general-purpose
language. But it's capable of a lot more than some people imagine. Some
people never really get below the surface to discover its depth.
