DR-16-0018: WML: need sort method for special characters [for today's call]

You may or may not be correct in your view that there is a user requirement
that fields be sortable according to the current locale. However, if there
is such a user requirement, it isn't currently met by OOXML or by
implementations. Support for specifying the current locale as the sort
method would involve an extension to OOXML and as such cannot be done by
amendment or revision of the standard, not by Technical Corrigendum, so this
is a big deal. Although this might be a relatively simple change, e.g. by
changing ST_SortMethod to allow any string (§18.18.73 of
ISO/IEC 29500-1:2016), it could not be made mandatory for implementations to
support these new values without breaking existing implementations, and if
they do not already do so, that suggests that there hasn't be much market
pressure that would persuade them to implement the enhancement.

I note that ODF doesn't appear to have this feature either (although it has
a similar feature – §19.865 text:sort-algorithm – for sorting text, e.g.
bibliographies), and in §19.685 table:order there is the following note:

	Note: Sorting is locale and implementation-dependent.

It is hard to avoid the conclusion that demand for this feature is very
limited, at least in office document applications.

I am not aware of the reason why this is so.

But anyway, why not then use the 14651 tailorable ordering in its template
form, which is equivalent to UTS#10 - as the universal sorting in OOXML?

I would think it was a user requirement that fields are sortable according
to the current locale, eg a list of names. 

Having the sorting order not being changeable creates troubles for users

best regards
