[Exist-open] Order By Case Insensitive

[Todd G. <tod...@gm...>]

I need case-insensitive order by functionality.

I've implemented a FLOWR order by using for $x in /requestPackage order by
fn:upper-case(fn:string($x/description)) return $x

I'm concerned about performance of the upper-case function.

I've found in documentation that collation support has not yet been
implemented and only unicode collation is supported.

I've found in the mailing list where Wolfgang points to a
configuation <indexer caseSensitive="no"> in
conf.xml but that he doesn't recommend this approach as it violates the
XQuery spec for string functions and operators.

I don't believe the full-text index is being used as an optimization of the
upper-case function.

What's the best practice for implementing case-insensitive sorting of
results?
