If you are running from the command line, it is possible to load multiple
packages by providing a semicolon-separated list of filenames in the -xsl
parameter. However, I don't think this is well documented or tested and it may
have restrictions concerning the order of packages.

What is documented and tested is using packages via the s9api XsltCompiler
interface; essentially you can compile a package into a CompiledPackage
object, and then make this available to an XsltCompiler using an importPackage
method.

This is a bit of a stopgap; packages are work in progress. We're thinking
about "classpath-like" mechanisms for the longer term.
