Grouping Documents into Classes
Making the Implicit Explicit
- Current Situation Strictly speaking, there is no concept of document classes in XML 1.0. Documents may share external resources - DTDs, entities, stylesheets, etc. - but this is on a document-by-document basis.
- Potential Grouping documents into classes centralizes control over document structures and presentation, simplifying large-scale changes. Applications could identify which document classes they were prepared to work with, and document classes could identify processors in which they could not be reliably opened.
- Drawbacks This approach would make it difficult for documents to be different where that is appropriate. (Styles are an easy override, but the rest is hard.)
