Michael Dürig commented on JCR-952:
-----------------------------------
XPath queries of the following form are now supported:
//element(*,nt:base) order by fn:lower-case(@foo)
//element(*,nt:base) order by fn:upper-case(@foo)
Meaning the property used for sorting is first converted to lower (upper) case
before comparison takes place.
> Support lower and upper case functions in "order by" clause

> The query languages should support lower- and upper-case functions within the
> "order by" clause. This would provide case-insensitive ordering of query
> results.
> Example: Find all "nt:base" nodes ordered by the "foo" property, but
> ignoring case
> In XPath:
> //element(*,nt:base) order by fn:lower-case(@foo)
> In SQL:
> SELECT * FROM nt:base ORDER BY lower(foo)
