For the sample DTD and document: - ---------------------------------------- <!DOCTYPE test [ <!--* TEST *--> <!ELEMENT test - - ((proof | theorem)*) > <!--* PROOF OF A THEOREM *--> <!ELEMENT proof - - (#PCDATA) > <!ATTLIST proof of IDREF #REQUIRED > <!--* THEOREM *--> <!ELEMENT theorem - - (#PCDATA) > <!ATTLIST theorem id ID #REQUIRED > ]> <test> <theorem id="theorem1">The earth is flat</theorem> <theorem id="theorem2">The stork didn't really bring me</theorem> <proof of="theorem2">If the stork brought me, I wouldn't need this belly button</proof> <proof of="theorem1">Someone told me</proof> </test> - ---------------------------------------- the following Jade stylesheet appears to solve the problem: - ---------------------------------------- <!doctype style-sheet PUBLIC "-//James Clark//DTD DSSSL Style Sheet//EN"> ;; Sample code in response to "Cross-referencing" post by Matthias Clasen (element TEST (make simple-page-sequence)) (element THEOREM (make paragraph (make sequence (literal (string-append "Theorem " (number->string (child-number)) ". ")) (process-children)))) (element PROOF (make paragraph (make sequence (with-mode theorem (process-element-with-id (attribute-string "OF"))) (process-children)))) (mode theorem (element THEOREM (literal (string-append "Proof of " (number->string (child-number)) ": ")))) - ---------------------------------------- The cross-referencing problem that gets me is how, in the absence of element-with-id, do you support an linking element such as the HTML <A> element that has content and the content is (one end of) the link to the referenced element. The only uses of the link flow object class that I have seen use the same with-mode and process-element-with-id combination as in this example, which does not preserve the content of the linking element.
