As commented in the change, the Import format was rewritten in 1.17, so I don't think it explodes on unrecognized tags from that version on. John, you can find the XSD of the export format in: https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/core.git;a=blob;f=docs/ex… (last version is 0.8). As for how they are really used, I think you will have to read the export code.
