If OPACXSLTDetailsDisplay is turned off, URLs in the MARC record (856 in MARC21) are not displayed. This appears to be a template toolkit migration issue: parameter is MARCURLS in perl, MARCurlS in template.

Marking as Passed QA (since I tested it when I wrote it). I assume that since this is a simple T:T, no one objects?
Tiny change easily tested pushed, please test and mark resolved
Found that this problem exists on the staff client side, as well. An additional renaming needs to be done to actually make the URL parse into the href attribute (otherwise, links appear, but point to page itself).
Follow up signed off on.
Again, pushing past QA because it's easy to test (tests included)
Pushed please test
Verified that URLs display correctly and work, both in opac and staff client, with XSLT-preferences set to off.
