Note that these “What if” questions all have unambiguous answers; any ambiguities result from buggy software, not from the XML spec. The reason for avoiding escaped markup within CDATA is not that it causes ambiguities in the data, but the many difficulties embedded markup causes for processing and that the well-formedness guarantee you get by using XML is thrown out of the window.
