Julian Reschke commented on JCR-3443:
-------------------------------------

a) Don't put new functions into the XPath namespace. If we add custom funct=
ions, they need to go into a Jackrabbit-specific namespace.

b) Normalization is tricky and depends on locales. I recommend looking at h=
ttp://www.unicode.org/reports/tr10/ and what kind of support Java already h=
as for that.=20

> Properties containing non-ASCII characters are not well collated in query=
 results
> There's only two allowed functions so far in XPath (fn:lower-case and fn:=
upper-case). There exists the equivalent LOWER and UPPER in SQL
> I propose to add a fn:normalize (resp NORMALIZE) function giving expected=
 results
