If you are using FOSI, here are two possibilities.
1. In the e-i-c for subpara title, code a specval to test for the ID attribute on the relevant subpara. For example:
specval attloc="subpara" attname="id" attval="#NE#\A123\"
charsubset
savetext textid="toc.app ..."
2. In the e-i-c for subpara title, code a savetext to save the title content, and code a usetext to call a pseudo-element to test the title content. For example:
savetext textid="exception-case-title.txt" conrule="#CONTENT"
usetext source="<exception-case-title.psu>,</exception-case-title.psu>"
In the e-i-c for exception-case-title.psu, code a specval to test for the content of the subpara title. For example:
specval attloc="#FOSI" attname="exception-case-title.txt" attval="#NE#\Exception Case Title\"
charsubset
savetext textid="toc.app ..."
Hope this helps!
