Extra element space in interleave in settings.xml

My settings.xml file contains the following lines:

space origin=“0. -14.37 0.” type=“cylindrical”
xml validation script creates the following error :
Validating settings.xml…[NOT VALID]
Extra element space in interleave

However openmc run without errors.

We haven’t done a great job keeping all the schema files up-to-date, so it’s not too surprising to me that the openmc-validate-xml script would fail on a file that is actually valid. I wouldn’t worry about the error if the openmc executable runs fine. In general, if you’re generating your XML files from the Python API, they should be valid.
