Seperating XSD and SDD fuels that confusion. I understand. I prefer "XSchema" as both the name of the standard and as the type of document. > >> 2.

I thought that that was redundant at first, too, but changed my mind. Being easy to parse and manipulate *as a schema* is maybe different than just being able to be parsed and manipulated as an XML document. For example, if we designed the links between elements badly, then it might be hard to verify documents, even though the schema is still in XML instance syntax. Nevertheless, I think that there is only a small chance of these goals having less than 100% overlap. Now that we seem to be adding one or two requirements per day, it might make sense to remove it. > >I don' think that there is a clear relationship to be described, at this > >point.

XSchemas are certainly not going to be a functional superset or equivalent of DTDs. I suppose it makes sense to view them as a complement. They are supposed to provide a simpler, more consistent syntax for doing most of the content and attribute verification that DTDs do.
