INPUT FILE: (XML)

<kala>
<havi>5</havi>
<kilu>3</kilu>
</kala>

The converter XSL:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="utf-8"/>

<!-- global variables -->
<xsl:variable name="nr_kala" select="/kala/havi"/>

<!-- producer-code -->
<xsl:template match="/">
<Result>
<xsl:value-of select="$nr_kala"/>
</Result>
</xsl:template>

</xsl:stylesheet>

===
The StylusStudio X15 with Saxon 9.5.1.8 gives the correct result as:
OUTPUT FILE:
<Result>5</Result>



The StylusStudio X16 with Saxon 9.7.0.3 gives an error message:
----
at: file:///y:/kalaconv.xsl 9
java.lang.RuntimeException: Error: at xsl:template on line 9 column 25 of kalaconv.xsl:

kalaconv.xsl (9, 25)
Error: at xsl:template on line 9 column 25 of kalaconv.xsl: XPDY0002: The context item for axis step (/)/kala is absent


===
Is there some bug or incompatibility between older and newer releases of the Saxon?
How to fix it?

Margus we have isolated the problem in the new Saxon 9.7.

When a TraceListener is register Saxon evaluates global variables before wiring the XML input.

We are working with Saxonica to find a solution.


Thanks for for the reporting the error and providing a useful test case

The most recent Saxon maintenance release (9.7.0.5) solves the problem.

We will update Saxon in our next update.
