@kinow I think this looks promising! I don't have much comments about the
implementation code, but just being able to use `ORDER BY arq:collation("fi",
?label)` seems that it would do a good job of solving my original problem. I do
like the way you have smuggled in the collation information so that it's
accessible to the `NodeValue.compare` function and it can thus rely on
`Collator.compare`, which should be pretty fast. Maybe there's a more elegant
way of doing that smuggling, but at least it seems to get the job done based on
your example results.
Did you by any chance test this with the [performance test
case](https://issues.apache.org/jira/browse/JENA-1313?focusedCommentId=15963023&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15963023)
that I wrote up earlier? I'd like to know how it compares to a plain ORDER BY
in terms of performance. I can test that myself too when I have a suitable slot
of time, but that might take a while since many deadlines are coming up in the
next few days...
