Yes. Although there were some recent additions to the laz_xmlcfg that
might be interesting for the fcl.

They use different xml units. The laz_ units were copied from the fcl
and changed to UTF8 for internal processing for speed reasons.
This was some years ago and the FCL units were optimized and extended to
parse more stuff. Two weeks ago I copied them again and changed them to
UTF8. They are named laz2_ and not yet used, because I discovered an
incompatibility for xmlconfig and special characters. This needs to be
fixed.

Note: The IDE fpdoc editor does not use laz_xmlcfg, but the underlying
xml units (laz_dom, laz_xmlread).
The FPDoc editor "lazde" uses the FCL xml.

That uses the FCL xml.
