Re: re: recursive looping and variable scope

I don't think, that a recursive template should be an issue, for the
error that XSLT processor is reporting, "for attempting to write to
the same URI". This should work fine, as long as URIs are different in
each recursive call.

The URI is generated with this code fragment:
<xsl:variable name="filename">policy_<xsl:value-of
select="$link1/jobs/job/@jobid"/><xsl:text>.xml</xsl:text></xsl:variable>

and this is dependent on variable, $link1 which is populated by
execution of the template, "getSchedule".

I suspect, there could be an issue with logic inside template,
"getSchedule" (which you haven't shared with us. can you please show
that if it's possible.) which is probably generating similar content
in different template calls.

B I assume Saxon will release its resources when they go out of scope -
especially with the saxon:discard-document function, but this loop is designed
to run an indeterminate period of time - theoretically forever.
