I suggest to reword the abstract as follows in order to state at the
very beginning that ITS
pertains to i18n and l10n and that is improves quality and lowers costs:

===
This document defines a standard for high-quality, cost efficient
internationalization and localization of schemas and XML instances (both
existing ones and new ones). On the one hand, the standard is defined
conceptually through the notion of data categories. On the other hand,
the standard defines implementations of these data categories as a set
of elements and attributes called the Internationalization Tag Set
(ITS).
The document provides examples of how ITS can be used with existing
popular markup schemes such as DocBook. Furthermore, the document
provides implementations for three schema languages: XML DTD, XML Schema
and RELAX NG.
Feedback related to this document is especially appreciated on the
general concept of ITS and the mechanisms defined for the selection of
ITS-specific information in documents and schemas.
===

FS> not implemented, not because I don't like it, but because I think
that we should need more feedback on such central positions from the
group. Please put this in bugzilla.

Resolution: This section is part of the introduction in the text reworded from Christian's and Richard's input and reviwed at the editor's call on Apr-07-06.

This can be closed, no action necessary.
