Cross-References with paragraph and section ids

For XML-first titles, where the Section IDs have been indicated on the title passport, use the paragraph and section id workflow for indexing and cross references within the text.

Only follow this topic if Section IDs have been requested via the title passport.

Example Title Passport

Add a milestone element as the first child element of paragraphs identified by paragraph ids (C1, C1.S1, C1.P1) in the manuscript. For ids at the chapter or division level, include this in the titleGroup/title/p. For ids at the paragraph level, include this as the first element in the paragraph.

                    //chapter/titleGroup/title/p

                    //*[name()[contains(., 'div')]]/titleGroup/title/p

//p

Give the milestone element a unique id attribute by following the instructions in the TCIs for id attribute capture here: IDs and DOIs. Capture the value of the unique section or paragraph id number in the num attribute. Capture the unit attribute with value para-id.

When the XML index is generated the xref element must contain the page number and the ref attribute must point to the corresponding para-id milestone id attribute.
