Document processing semantics (ODF 1.2 CD01)

["Alex Brown" <alexb@griffinbrown.co.uk>]

Dear all,

1.4.5 has:

----begin extract
If a foreign element has a <text:h> or <text:p> ancestor element and is a child element of an element which may include <text/>, then the element's content may be interpreted by conforming OpenDocument processors, and the document itself shall be valid against the OpenDocument schema if the unknown element is replaced with its content only.
----end extract

* does "a child element of an element which may include <text/>" mean "a child element of an element _declared to have_ mixed content" ? (i.e. are  we talking about a RELAX NG declaration here, not a <text/> element in the instance?)

* What does it means for an element to be "replaced with its content only". The string value of that element? its text nodes? the subtree it contains? - or is the process to be applied recursively to any descendant foreign elements of such an element?
