Thanks so much for replying (I have been fighting this stuff for over a week).
Do you happen to know if the "external subset" returned from here is applied before the actual, physically-present internal subset? In other words, if I have: <!DOCTYPE ... [ <!ENTITY verison "VERSION"> <!ENTITY today "TODAY"> ]> Will the net result of injecting these value "again" be: <!DOCTYPE ... [ <!ENTITY verison "1.1"> <!ENTITY today "June 18, 2009"> <!ENTITY verison "VERSION"> <!ENTITY today "TODAY"> ]> or vice-versa? I found that xerces uses the first declaration, is why I ask...
