8f44fb5e "Mark Base window titles for
localisation" localized some uses of ooSetupFactoryUIName in
officecfg/registry/data/org/openoffice/Setup.xcu, but failed to mark the prop as
oor:localized="true" in officecfg/registry/schema/org/openoffice/Setup.xcs.  (So
some arbitrary localized version of the prop would win at runtime, potentially
displaying certain window titles in wrong languages.)

Other uses of ooSetupFactoryUIName in Setup.xcu (for "Calc", "Impress",
"Writer", etc.) have never been localized, and are probably not meant to be
localized.  AFAICS, irrespective of oor:localized="true" in Setup.xcs, their
values not being marked with xml:lang="en-US" in Setup.xcu will mean that they
will not appear in
translations/source/*/officecfg/registry/data/org/openoffice.po and will not
accidentally start to be translated after this commit.

(Theoretically, inconsistencies between oor:localized in xcs and uses of
xml:lang in xcu could statically be caught at build time, e.g., with
officecfg/util/sanity.xsl.  However, those checks work on each XML file
individually, so don't have the schema information available when looking at
the data in the xcu file.  And those checks are written in XSLT, which makes
writing new checks rather, erm, unpleasant.)
