Yes, then they're not maintained. And unmaintained overlays tend to
contain even more broken ebuilds than others.

How about using the power of xml and version the schemas? As long as the
metadata-file specifies the respective dtd/xsd/relaxng you know exactly
how to validate (and parse) it and may apply a xsl-trafo if necessary to
convert it to a new format on the fly. As long as you keep using xml you
can then change the complete format in a new schema version.
