Well, AFAICT, it's not really empty from a SAX parser's
point of view. It does contain a text-node, but this is
completely ignored by FOP. The SAX characters() events are
only handled for FOs that can contain #PCDATA.
Mmh, I'm not sure to understand. The document contains
some:
<fo:instream-foreign-object/>
as well as some:
<fo:instream-foreign-object>...</fo:instream-foreign-object>
I guess you only saw the later. Furthemore, if I
understand right ยง6.6.6 (mmh, ok, born to be a problematic
paragraph :-p):
Yep, my mistake, I only saw the latter. Anyway, what I mean is that the
SAX Parser used with FOP will report those three '.' characters. That
is: any compliant XML parser MUST report those characters to the
application. Only FOP does nothing with them, and those characters are
ignored.
Contents:
The fo:instream-foreign-object flow object has a child
from a non-XSL namespace. The permitted structure of
this child is that defined for that namespace.
So it is required to an IFO to have a child element, isn't
it?
Yes. Exactly one child that is not in the XSL-FO namespace.
And to don't have non-whitespace #PCDATA. Right?
Hmm... Yes, if I catch your intention correctly.
So an FO validator would have to report an error for both the
above IFOs, isn't it?
I'd think so, yes. OTOH, if you have an i-f-o that contains some text,
and then a foreign XML node, I'd assume that a warning would suffice...
I disagree, although not enough to resubscribe to FOP-DEV and veto such
a matter. PCDATA isn't allowed for fo:i-f-o. Those FO's which may have
PCDATA are expressly defined in the XSL specification.
I would rather every FOP-accepted XSL stylesheet be accepted by every
commercial processor, than have the reverse, as the reverse would
require watering down our validation to the extent that a FOP-accepted
stylesheet is no longer a guarantee of XSL compliance (or anything
else.) "If your stylesheet is accepted by FOP it is as good as gold" is
a nice selling point.
