But, can the SMIL community decide the rule? Since this issue is XML-generic, wide range of consensus should be required. Also, it might be a problem that usual XML validaters cannot detect SMIL-specific syntax errors. For example, while <switch> in <head> can contain only <layout>'s, the SMIL DTD dose not express this constraint. Then, a SMIL-unaware parser fail to detect that type of violation. This problem concern what is a valid SMIL document, or what is a syntax checking in SMIL. If a good XML Schema is achieved, a precisely defined XML validity will be equivalent to the SMIL validity; ... I expect so. Thank you, -- HIYAMA Masayuki <hiyama@glocom.ac.jp>
