As Stephen says the checker currently only validates versions 1.0 to
1.4 of the CF convention.
I was unaware that CF-1.5 had been officially released. I now see that
the CF-1.5 document was added a couple of weeks ago. Guess I must have
missed that announcement somehow. :-(
Once I have a list of all the differences, I will implement them in the
checker as soon as I can and announce the update on the cf-metadata
mailing list.
Cheers,
Ros.
