[osis-core] User manual bug list - 91 Lang codes

Resolution: 
We cannot change the schema for xml:lang as it is not in our namespace
and because it must be understood by XML parsers it is likely hardcoded
to reflect the current xml.xsd schema from the W3C.

The accepted practice for Ethnologue codes is xml:lang="x-SIL-PDG" and
it is valid.
