Upshot, two different "versions" of the schema are being used.

Subject: xlink incompatibilities


I see there are several different versions of xlink.xsd floating around
all claiming the same targetNamespace="";.

EAD refers to
METS refers to
MODS refers to

When I try to embed EAD and MODS inside one METS file
and validate such a construct it obviously fails.

Are there any plans to synchronise the XLink dependency so that it
resolves to one and the same schema?
