Description

The following stylesheet outputs B D A C E Z in Firefox and A B C D E Z in Chrome (tested on https://martin-honnen.github.io/xslt3fiddle/).

Not sure this has to do with collations, but I added one as suggested by Norm.

Note that there is one element without dct:title which might be part of the cause. After removing it, Firefox also returns A B C D E Z.
