One interesting angle that has come up in PF is the way header nesting is enforced in ISO HTML. http://purl.org/NET/ISO+IEC.15445/Users-Guide.html#h1 This is a schematron-like scenario where a tree transform is performed to insert virtual DIVs corresponding to the headers, as an instrumetality or mechanism for making the proper nesting of headings DIVs easy to describe and check. ISO HTML documents are supposed to be checked by this rule, with its implications of authoring-session evaluation processing, and virtual-container structure in the document, even 'though the associated virtual containers are _not_ included in the markup as shipped. One side effect of this related to the session on Apr 27 on structural navigation is that if we want to say that a UA should provide hierarchical navigation corresponding to the headers in the document, then there is already in the ISO literature a reference algorithm defining what these structural scopes are.
