There >is no reason to reinvent regular expressions in XML element syntax. Surely we cannot judge syntaxes independently of usage scenarios! There may be different optimal syntaxes for * data-entry of content models * data-transmission of content models * document of content models * creating user interfaces for interactive editors using a schema, etc. I certainly like entering content models using XML-style content models. But I also like viewing content models as collapasable tree (you can do this using my DTD2DDML converter and IE5 default stylesheet). My complaints about using instance syntax have always been the verbosity question: it is rediculous if the size of a schema dwarfs the size of the transmitted documents (for use by general applications): a silly step backwards. This is why I think the best model for XML Schemas is that they will be used as master files from which smart forms (for data entry) and DTDs (for content model validation) and XSL (for other kinds of validation) can be automatically generated.
