Re: [relax-ng-comment] Other separators for list element

[James Clark <jjc@jclark.com>]

This is a reasonable suggestion.  We did consider it but decided it was on
the wrong side of the 80/20 line for 1.0.  One reason is that many people
feel that the way to represent a structured object (such as a list) is to
use markup.  We included <list> only because this is well-established by
other schema languages such as DTDs (NMTOKENS, IDREFS etc) and XML Schema.

The extensible datatype library mechanism could help you here if you really
need this. You can add a datatype library that includes a list datatype with
a parameter that's a separator and other parameters that describe the
members of the list.
