sounds nice, except:

this should generally be the latest ODF version that the LO release
supports, and if you select to store your files in a specific,
non-extended version in Tools->Options you don't (or at least shouldn't)
get any extensions... so what's the benefit of tracking this?

i'm not sure if this is so useful - you can tell the validator if you
want to check strictly against the schema or allow extensions:

 -c: Check conformance (default for ODF 1.2 documents)
 -e: Check extended conformance (ODF 1.2 documents only)

if the extensions are properly name-spaced then validation with -e
should not report any errors, and validating a document stored as
"extended" with strict conformance will inevitably report problems, so
don't do that.
