#393 clarifying guidelines on defining namespaces


Section 23.2.2 says:


In a TEI-conformant document, it is assumed that all attributes not explicitly labelled with a namespace (such as, for example xml:id) also belong to the TEI namespace, and are defined by the TEI.

This implies that any other modification (including a renaming or reversible modification) must either specify a different namespace or specify no namespace at all.


Does "no namespace at all" mean using


? I assumed it meant not using @ns on the element, but that would contradict the first paragraph. It would be good to clarify this.

Later in this section, the Guidelines say, "Similar methods may be used if a modification (clean or unclean) is made to the content model or some other aspect of an element, or if it declares a new element."

The following are unclear:

a) Similar methods to what? Are we just talking about use of @ns?

b) In what case(s) would you define a new namespace for a clean customization of an element? As far as I can tell from the discussion in chapter 23, you never declare a new namespace for a clean customization.

    "no name space at all" means that you have declared your new attribute as having no name space, i.e. you said "@ns="" in its declaration, and consequently , in the document instance, you may refer to it without a prefix.

    The sentence beginning "Similar methods..." is rather misleading, not to say vague. I have reworded it as follows:

    <p>Similar considerations apply when modification is
    made to the content model or some other aspect of an element, or when
    a new element is declared. Clean modification requires that all such
    changes be explicitly labelled as belonging to some non-TEI name space.</p>

    I've marked this as "fixed" but left it open in case you want to comment further.

    I like the revised version, but shouldn't the second sentence in the revision ("Clean modification requires [. . . .]") include at the end of it the phrase "or to no namespace at all"? This would correspond with the sentence beginning "This implies that any other modification [. . . .]" (which I have found confusing because of the way English syntax generally allows "declares no namespace" and "does not declare a namespace" to be interchangeable).

    Well, I would argue that "no name space" is included in "non TEI name space" but I've added the phrase suggested at rev 10298 anyhoo and am now closing the ticket,
