Unfortunately I can't remember what doc that was; what's your source? ISO 10646 and other ISO character sets uniformly use 'quotation mark' -- which is what the comment in the entity set says -- for the " symbol, and 'apostrophe' for the ' symbol, and 'grave accent' (and possibly something else indicating its use as an open single quote) for the ` character. That seems to me reason enough to believe the " should be treated as ", and ' as '. >I am very pleased with the decision to reduce the list of predefined >entities to a manageable number. I'm not actually sure why any beyong >< and & are needed, although > is good for symmetry. providing quot and apos makes it possible for attribute values to contain both characters; it also allows the user to choose which delimter to use, if they prefer to use the same one all the time. Strictly speaking, one would have sufficed. >The current situation is so much of an improvement that it seems almost >churlish to ask this, but why is ' included when it is not >recognised in plain text? It is recognized in literals and may need to be escaped there. Michael
