Hi Mukul,

One of the things that is required for using XSLT packages is that you need
to set up the processor to find them.

I can offer an example: the project 'ajp' is an XSLT package for which an
example XSLT then uses the package:

https://github.com/xmljacquard/ajp

In SaxonHE for java, you need to compile the innermost packages first and
then add them to the compiler to compile the using packages, up to the
outermost using package.

As an example from
https://github.com/xmljacquard/ajp/blob/main/src/main/java/org/xmljacquard/aj
p/XsltXpathEnvironment.java

The inner package is compiled specially using "compilePackage()" and then
imported into a compiler using "importPackage()".

    public static XsltCompiler getXsltCompiler(final Processor processor)
throws SaxonApiException {
        final XsltCompiler compiler    = processor.newXsltCompiler();
        final XsltPackage  xsltPackage =
compiler.compilePackage(getPackageSource());
        compiler.importPackage(xsltPackage);
        return compiler;
    }

The returned compiler is then used to compile the "using" package.

I'm hoping that helps and best regards

-alan
