As Stephen says the checker currently only validates versions 1.0 to
1.4 of the CF convention.<br>
<br>
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. <span class="moz-smiley-s2"><span> :-( </span></span><br>
<br>
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.<br>

Cheers,<br>
Ros.<br>

works so I'm
going to forward general questions to cf-metadata and Ros

answer Luca's question below -- The checker expects the
version option to be
between "1.0" and "1.4". I'm not sure what features would
need adding to support 1.5.<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size: 11pt; font-family:
