Please do not make inline comments in the proposal - use StructuredDocumentDiscussion to make comments. Jr. Problem Web sites of any size are maintained by a variety of people working with different tools. Since getting people to change tools is about as difficult a feat of social engineering as is known, people should be allowed to use their preferred tools whenever feasible.
Content needs to be structured to allow a separation of content and presentation.
StructuredText has proven very useful for basic structuring in the world of Zope, but XML is rapidly taking over the world for this purpose. Tools which support working comfortably with XML are seeing increasing adoption. It would be really good if existing StructuredText documents could be handled by such tools, and if new content could be created using those tools while maintaining compatibility with existing applications. This is valuable because users can then use tools they are already familiar with. If a document is created using an inexpensive markup like StructuredText , then edited using an XML editor, it may be difficult or impossible to move the document back to StructuredText .
