Every day, addon planes are released for FSX & P3D with XML syntax errors in their XML gauges & models, resulting in expected functionality, not working.
While there is a crude XML Syntax Checker, that can be turned on in the the prepared.cfg file, the error reports from that syntax checker, are typically near to useless to identify wherer the error is.
ie: Error in abc.xml - Possibly a missing space !
No line numbers, and very seldom the context in which this error occured.
Please could the P3D developers at Lockheed apply some thought to either improving this built in checker, or providing a better external syntax checking tool, that gives more meaningfull error reports.
Benefits might be.
(1) Developers are able to far more efficiently find and correct XML syntax errors.
(2) For $50, I could see most serious developers, buying P3D, just to be able to better test their FSX XML !!
