some basic xpointer questions from Eve L. Maler on 2000-06-12 (www-xml-linking-comments@w3.org from April to June 2000) (original) (raw)

Ahem. Good points. I think we need to count this as a comment against XPointer (Daniel, can you add it to the issues list?), and discuss it as soon as our schedule allows.

In last week's XML Core WG's telcon, some very basic questions about xpointer arose.

How does the fact that "xpointer points into a resource whose mime type is XML" reconcile with the idea that xpointer points into an Infoset (or, specifically the "data model" defined by XPath, since XPath preceded the existence of an official infoset)? Is it just an error to label a resource as "XML" if it doesn't have an infoset? (Note that there almost certainly will be XML 1.0 well formed documents that do not have infosets, such as those that contain names with colons that are not namespace-conformant. This might even include documents with relative namespace names, depending on the outcome of the Great NameSpace Debate (GNSD).)

Are XML external parsed entities resources of mime type XML or not? If so, does xpointer point into them? Do external parsed entities have an infoset, or are they just part of the infoset of the complete XML document that references them?

If xpointer is used to point to an external parsed entity, what does the xpointer "/1" mean? How do you point to the bar element in:

abcd and xyz

or the string "move" in:

A bold move!
