2. Technical agenda

2.1. JNodes/Generalized path expressions

Last week, we agreed to return to this with an eye towards accepting it unless there are objections.

See PR #2083: 2054 Generalized Path Expressions and PR #2031: 2025 JNodes

(I believe that #2083 subsumes #2031, so accepting #2083 should also close #2031.)
