Thank you, Dr. Kay,
It almost worked from the command line, but this time I got:
C:\xml\XSLT3.0>"C:\Program Files\Java\jre7\bin\java.exe" -Xms1024M
-Xmx1024M -jar C:\xml\Parsers\Saxon\Ver.9.6\saxon9ee.jar -t

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.

Hi,
Using the trial version of Saxon 9.6EE and the example package from
the latest XSLT 3.0 Last Call, I am trying to produce a simple,
running example:
using-package.xsl:
==============
<xsl:package name="http://example.org/complex-arithmetic.xsl";
package-version="1.0" version="3.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:f="http://example.org/complex-arithmetic.xsl";>
<xsl:use-package name="complex-arithmetic"/>
<xsl:template match="/">
<xsl:variable name="vComplex1" select="f:complex-number(1, 0)"
as="map(xs:integer, xs:double)"/>
Real: <xsl:sequence select="$vComplex1(0)"/>
Imaginary: <xsl:sequence select="$vComplex1(1)"/>
</xsl:template>
</xsl:package>
complex-arithmetic.xsl:
=================
<xsl:package name="complex-arithmetic"
package-version="1.0" version="3.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:f="http://example.org/complex-arithmetic.xsl";>
<xsl:function name="f:complex-number"
as="map(xs:integer, xs:double)" visibility="public">
<xsl:param name="real" as="xs:double"/>
<xsl:param name="imaginary" as="xs:double"/>
<xsl:sequence select="map{ 0:$real, 1:$imaginary }"/>
</xsl:function>
<xsl:function name="f:real"
as="xs:double" visibility="public">
<xsl:param name="complex" as="map(xs:integer, xs:double)"/>
<xsl:sequence select="$complex(0)"/>
</xsl:function>
<xsl:function name="f:imag"

<xsl:param name="complex" as="map(xs:integer, xs:double)"/>
<xsl:sequence select="$complex(1)"/>
</xsl:function>
<xsl:function name="f:add"
as="map(xs:integer, xs:double)" visibility="public">
<xsl:param name="x" as="map(xs:integer, xs:double)"/>
<xsl:param name="y" as="map(xs:integer, xs:double)"/>
<xsl:sequence select="

f:real($x) + f:real($y),
f:imag($x) + f:imag($y)"/>

</xsl:package>
When I run Saxon 9.6 on using-package.xsl, I get these error messages:
Saxon-EE 9.6.0.1J from Saxonica
Java version 1.7.0_51
Using license serial number Vxxxxxxxxxxxxxxx
Error at xsl:use-package on line 6 column 47 of marrowtr.xsl:
XTSE3000: Package complex-arithmetic was not found
Error at xsl:variable on line 9 column 101 of marrowtr.xsl:
XPST0017 XPath syntax error at char 0 on line 9 in {f:complex-number(1, 0)}:
Cannot find a matching 2-argument function named
{http://example.org/complex-arithmetic.xsl}complex-number()
Stylesheet compilation failed: 2 errors reported
What should I do in order to make this simple example run as expected?
It is not clear to me how finding a package given its name works -- I
also tried importing complex-arithmetic.xsl into using-package.xsl,
but got this error:
"Error at xsl:import on line 8 column 46 of marrowtr.xsl:
XTSE0165: Included document complex-arithmetic.xsl is not a stylesheet"
Any guidance how to produce a running example is enormously appreciated.
