It also works reasonable well with (also included) xml files. Personally I never use synctex but for some projects it came in handy for authors (think of proofing xml files with hundreds of nested inclusions and files in a rather branched tree.) Of course you can expect a similar performance hit as normal synctex but commenting the above line in production results in zero overhead. Using the syntex flag on the command line (--synctex=context will work) can be messy.

With 2017.07.17 00:20 the issue seems to persist.
