Hi,
I was wanting to continue writing xml documentation in which
the well-formedness constraint on internal general entities
does not result in a fatal error on parsing with the xerces XMLReader.
That constraint says that document structures must start and end within
the same entity, whereas I would prefer, for legibility of the
authoring process, to split the start and end tags of overly verbose
nested tags into two separate entities validated after the whole
document has been expanded.
What do I have to do to switch off this particular validation
mechanism in xerces?
You cannot disable checking and error reporting for any of the
well-formedness constraints. Well-formedness checking [1] is required by
the XML spec. Violations of well-formedness constraints are fatal errors.

Michael is of course correct. A solution to Doug's problem might
be to not split the start and end tags but rather turn the entire
descendant content of that element into its own separate entity,
keeping the start and end together as per the XML well-formedness
requirement, while using a parameter entity switch in the internal
subset to turn on or off expansion of a predefinition of the
"overly verbose" entity, substituting an entity containing a short
catch-phrase (e.g., "UNEXPANDED TEXT" or something akin), i.e.,
substituting a small phrase for a link to the real content. Then
when you want the real thing, you just alter "INCLUDE" to "IGNORE"
on the marked section. If you need examples of this kind of
syntax, look inside pretty much any DTD (the modular XHTML DTDs
have hundreds of them).
Not sure if this solves your problem exactly, but this is basically
how a similar problem is solved in industry (like in Sun's documenta-
tion department).
