SAX characters event and external entities

SAX parsers may return all contiguous character data in a single
chunk, or they may split it into several chunks; however, all of the
characters in any single event must come from the same external entity
so that the Locator provides useful information. [1]

How much of a "violation" would it be to have a caching XMLFilter that
would report all contiguous character data in a single event,
including across entity boundaries?
