  Ah yes, I remember now, we did have problems with ThreadLocal caches in the past. I'm sorry, I really can't roll back to remind myself exactly what those problems were and how they were resolved. You need to move forward!

  Michael Kay We can't give you very much help unless the problem can be reproduced on a more recent software release.
  I would suggest taking a heap dump and analyzing it to see which Saxon objects are accounting for the memory usage, and what refe...

  I've introduced an interface PushableFunction, implemented initially by UnparsedText; if a function is pushable then it has a process() method that sends its result to an Outputter. We invoke this from xsl:value-of in the case where the ... Feature #4223: xml-to-json() output is not streamed

  When the input to the xml-to-json() function is streamed, and the resulting string is sent straight to a Serializer, we should stream the text output to the serializer rather than building it up in a buffer in memory and only writing it ...

  Michael Kay I've got this to work -- for one test case, anyway -- by extending the Outputter interface with a `getStringReceiver()` method which returns an object that allows the contents of a string (xs:string atomic value) to be supplied increment...

  Fixed by a simple change to the table of function signatures. Bug #4225 (Resolved): Imprecise type inference for xml-to-json() function

  The static type inferred for the result of the `xml-to-json()` function is `item()?` rather than `xs:string()?`.
  This is unnecessarily imprecise, which means that optimizations on the enclosing expression don't kick in.

  I've been trying to generalize the JsonReceiver code so it can emit output text incrementally rather than gathering it in a string buffer. It's proving tricky, because in a case like
  ~~~
  <a>X{xml-to-json($var)}Y</a>
  ~~~
  the valu... Feature #4223: xml-to-json() output is not streamed

  Bug #4222 (New): [xslt30] Visibility of xsl:param

  The XSLT 3,0 spec makes confusingly inconsistent statements about the visibility of global parameters.
  * The grammar for `xsl:param` does not allow a `visibility` attribute
  * In §3.5.3.1, under `xsl:expose`, we say "The visibility ...

  Thanks for reporting this.
  In the command line help, I don't see either -pipe or -qversion in 9.9. The -pipe option was last seen in 9.8, while -qversion was last seen in 9.7.
  -TB is available in 9.8 and 9.9 but not in 9.7.
