My thought is once we agree on Moo or Mouse, it'll be easy to rewrite this.

I made up the ind1=z convention. Any letter would work, since the point is just
to make sure that particular tag is invalid in all MARC flavours, and letters
are not allowed in indicators by the ISO standard.

I am not 100% sure that the UNIMARC XSLT does not need to be modified. However,
when I tested it, I didn't see the see-from headings. If they're showing up for
you, I'm happy to do a follow-up modifying the UNIMARC XSLT.

Subjects are not displayed in the results, so this is a non-issue.

It would be easy to do by adding additional filters. This patch, of course,
adds rejected forms rather than see also forms to the record. I am currently
working on a suggestion plugin for broader/narrower/related terms, the patch
for which I will attach to bug 8211.
