I agree with Joshan.

I do not really know how a working MusicXML engraver would help me to 
make my own engraver better. Of course I could test specific cases, but 
it does not provide a systematic way to evaluate the quality of my own 
renderer.

What was really helping me so far for the Zong! open source music 
notation project, is the Unofficial MusicXML Test Suite from the 
Lilypond project,
http://www.lilypond.org/doc/v2.18/input/regression/musicxml/collated-files.html
Unfortunately, there are some errors in it, Lilypond does not support 
some features (so some result images are unusable) and it wasn't 
extended for a long time. But a test suite in this style (MusicXML input 
and expected result image) seems to be perfect for me to measure 
quality. What tests/benchmarks do the other MusicXML engravers use?

What I'd like to see is something like "My app reaches 164/200 points in 
the official MusicXML rendering benchmark. 30 points are not implemented 
yet, 26 others currently fail.". And a list with the detail images.
(And the best app will be the unofficial reference app...)

Bye,


Andi
