Published cross reference origin text (add \xop ...\xop*)

[klassenjm]

Proposal

• Add character marker pair \xop …\xop* for “published cross reference origin text”.

A companion USX 3.0 proposal exists at: ubsicap/usx#9

Details

In some translation texts, the content intended to be published in the position of the cross reference origin text \xo does not follow the typical <chapter>``<separator>``<verse> pattern. A origin reference of this pattern is required for validation of the cross reference location. An additional new marker is therefore required in order to supply the content intended for publishing, similar to \cp and \vp ...\vp*.

Example

Bulgarian USFM 2.5 compliant text.

\x - \xo 1:1 \xt 4 Царств. 14:25.\x*

which should be rendered in a published form as:
Гл. 1.(1) 4 Царств. 14:25.

Proposal using \xop (note that this example follows the common USFM practice of not explicitly closing the first level of note character markers)

\x - \xo 1:1 \xop Гл. \+bd 1.(1)\+bd* \xt 4 Царств. 14:25.\x*
