Subject: Re: [docbook] Proposal: stop shipping entity sets with DocBook V4.4

To the Pro list, you might also add:

  - named entities are a legacy convenience feature, inherited from
    SGML, that users should not be encouraged to continue using

I personally think we ought to be encouraging users to move to doing
their authoring and validation using tools that support Unicode and that
are driven by modern schema languages (RELAXG NG and W3 XML Schema),
which don't support named entities unless you declare them in an
internal DTD subset in each and every one of your doc instances.
