Introduction of @for into the Text Attributes Collection

Background

The for attribute, is defined in HTML 4.01 to bind LABEL (or multiple
LABELs) to a form control using an IDREF. While the adoption of XForms
as the XHTML2 XForms Module relegates the original use of the for
attribute obsolete, the for attribute should be re-introduced into the
XHTML2 Text Module to provide textual expansions and explicit bindings
between labelling text and the text it labels.

Proposed

1. That the for/id mechanism, which is already broadly supported in
user agents and assistive technologies, be repurposed and extended
in XHTML2 to provide explicit bindings between labelling text and
the object or objects that text labels;
2. That the for/id mechanism serve as a means of re-using values for:
1. ABBR
2. D (the single letter "dialogue" element)
3. DFN;
3. That the for/id mechanism serve as a means of binding a quotation,
contained in the Q element, and a corresponding CITE declaration
which identifies the source of the quote;
4. That the for/id mechanism serve as a means of marking text which
has been inserted, contained in an INS, and that which it is
intended to replace, contained in a DEL tag, as illustrated below;
