As Paul later pointed out is that they'd have to define a mapping from their custom syntax to an XML infoset which in itself isn't hard. > | Of course they could define a mapping from paren-prefix notation to > | XML > | infoset but that strikes me as extra effort with no payoff. > > The payoff could be an easier syntax ( => simpler parser ) > for the map. You are only focusing on one tiny aspect of the implementation. An XML parser that doesn't have to deal with DTDs is not difficult to implement so the payoff there is small. On the other hand, creating transformers from their custom syntax to XML syntax or XML object models so that they get the benefits of XSD or XSLT is an unecessary step that adds runtime overhead and would involve their users having to learn separate syntaxes and other problems. For instance, if a stylesheet or validation error occurs in their custom syntax should the offending data be shown as XML or in their custom syntax? -- PITHY WORDS OF WISDOM Any given program, when running, is obsolete.
