  Reopening this bug issue. Feature #5967 (In Progress): allow to set language version 4.0 for XPath evaluation

  SaxonJ EE supports setting the XPath language version to 4.0 (for the currently experimental XPath 4.0 support); it appears that SaxonC so far only allows that for XQuery (where a `lang` argument has been added to the API) but it so far ...

  O'Neil Delpratt Yes that is the problem.
  And because of comment #7 the following hack/workaround works for me:
  ``` python
  xpath_proc.set_property('lang:', '4.0')
  xpath_proc.set_property('lang', '4.0')
  ```

  I've got Saxonche working in a Python environment where I'm calling it from a little TKInter GUI that provides a logging panel for reflecting the messages from processes run by the GUI.

  That is correct, a custom handler is not currently supported in python. Saxon/C Help and Discussions: RE: Integrate Python logger or redirect stdin and stdout?

• 
  O'Neil Delpratt There are a number of options . Yes the default is to output to stdout/stderr.
  You can turn them on/off, save to file or capture them and return them in an PyXdmValue.
  To start with see: https://www.saxonica.com/documentation12/index...

  Moving this project to the SaxonC project Bug #6392: Memory leak in PySaxonProcessor (Python)

  Consider the following code fragment:
  from saxonche import PySaxonProcessor
  import psutil
  count = 0
  prev = (mi := psutil.Process().memory_info)().rss
  for _ in range(100):
  with PySaxonProcessor(license=False):

  Yes I am not surprised as its the same base code across the three products. We have a fix for this. Bug #6381: set_unprefixed_element_matching_policy(1) doesn't seem to work

  I wrote the following Python code making use of `set_unprefixed_element_matching_policy(1)` on an `PyXPathProcessor`:
  ``` python
  from saxonche import PySaxonProcessor
  with PySaxonProcessor() as saxon_proc:
  print(saxon_proc.ve...
