I tried to debug with the Oxygen XSLT debugger this:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs" version="2.0">

    <xsl:template match="/">
        <xsl:value-of select=
            "for $x in .
               return
                  if ($x//y)
                     then $x//z
                     else '42'"
        />
    </xsl:template>
</xsl:stylesheet>


And it was not possible to set a breakpoint on any of the lines of the
XPath expression, nor to step through the subexpressions.

Does Saxon really provide enough data via its debugging API to support
such debugging?
