Hum, i *don't* want to validate while parsing.
On the contrary, i want to completely ignore the external subset,
even if it's present, just parse in the document.
Precise: The documents are contained in memory blocks that
are provided from our OS abstraction layer (therefore i
access them via an I/O parser context with read callbacks that
use APIs from that layer).
While parsing i *can't* determine a base path for that documents,
so, if "parseCtxt->loadsubset" is true (the default), the
parser complains about that he can't load the external subset
(and for sure he's right) and fails.
But i'm able to provide a base path after parsing (don't ask why,
it's a long and sad story...).
Using an own external entity loader, i want to validate the
document subsequently.
Well, as i said, setting "parseCtxt->loadsubset" to false
works for me, i just want to know if it's the appropriate
way to do so.
