Description
- Is the trace supposed to mark xsl:accumulator as hit?
- Is the trace supposed to mark xsl:accumulator-rule as hit?
- I definitely expect descendant elements of xsl:accumulator-rule to be marked as hit, and I'm not seeing them in Saxon 12.4. Saxon 9.9.1.8 correctly lists the descendants of xsl:accumulator-rule.
I'm attaching a file that includes the code, the Saxon arguments I used, and the traces I got from Saxon 9.9.1.8 and 12.4.

xsl:accumulator evaluation is effectively in parallel with normal execution (the details depend on whether you're streaming or not) so it would not be possible to mix any trace output with that of other instructions. There is a completely separate mechanism for tracing accumulator evaluation: use saxon:trace="yes" on the xsl:accumulator declaration. (But again, it's probably under-tested.)

I've been looking into this; it's not a quick fix. I'll look at it as a possible enhancement for a major release.
