/ Innovimax SARL <innovimax@gmail.com> was heard to say:
| [[
| 5.14 p:document Element
| The parser which the p:document element employs must be conformant
| Namespaces in XML. It must not perform validation. It must not perform
| any other processing, such as expanding XIncludes.
| ]]
|
| [[
| A.1.9 Load
| Load attempts to read an XML document from the specified URI. If the
| document does not exist, or is not well-formed, the step fails.
| Otherwise, the document read is produced on the result port.

I think we need 'validate' and 'namespace-support' options on load.
The former should default to 'no', the latter to 'yes. Implementations
should be free to throw a dynamic error if namespace-support='no'
is requested and they do not support documents that aren't namespace
well-formed.

Alternatively, we could outlaw documents that aren't namespace
well-formed altogether. I could live with that.

| I see two points :
| 1) DTD Validation
| 2) Non namespace well-formed
|
| 1) could easily be an option "dtd-validation" (true/false). But we may
| need to have access to a catalog.

For the moment, I'm happy to leave catalog support as a quality of
implementation issue. But we'll come back to the p:catalog proposal
soon.

| 2) is already more tricky :
| --> Is there really case where a well-formed file could be converted
| to a namespace-aware-well-formed file ?
| The only thing I can imagine is proposing an option to replace ":" by
| another char (may be with colon-as-first-char-replacement and
| colon-replacement)
| But is this really worth ?

I don't think it makes any sense to attempt to transform a namespace
not-well-formed document automatically into something else. The
question is really, do we think it's worth allowing them at all.

Most modern technologies require namespace well-formed documents.

                                          norm
