Greets,
Has there been any discussion in the past about custom sources for
document entities(alternatives to DTD specified entities)?
Yes, I do have something specific in mind, a pair of PIs:
<?xml-entity name='ent' value='val'?>
and
<?xml-entities type='text/xml-dtd' href='someURI'?>
<?xml-entities type='text/xml-entities' href='someURI.xml'?>
The first form is for simple, quick, in-document declarations, and the
second is for external resources, meant for large[r], reusable sets of
entities.
As the existence of the 'type' pseudo attribute implies in the second
PI, processors should be capable of handling different types of sources,
whether DTD, a custom XML entity source, a newline seperated list of
assignments, or whatever.[Preferrably through a plugin system of sorts
:]
A format like this seems particularly natural/appealing to me:
<entities>
<ent_name>entity content</ent_name>
<another_ent>foobar</another_ent>
</entities>
(of course in the referencing document: &ent_name; and &another_ent;)
Perhaps there should be scoping limitations depending on where the PI
appears.
With the many validation mechanisms available today, it seems a bit
obtuse to rely solely on DTDs for sources of entities.
Thoughts, or am I beating a dead horse that I've never seen before?
