Hi John
Rather than invent another namespace separator - with potentially
unforeseen side-effects - might an alternative solution be simply to use
XML itself? For example:
char time(record=63, time_len=21);
time:long_name = "forecast date and time";
time:xml_attr = "<dc:title>Field Guide To CF</dc:title>
time:xml_attr = "<dc:creator>J R Luser</dc:creator>
or
char time(record=63, time_len=21);
time:long_name = "forecast date and time";
time:xml_metadata = "<dc:title>Field Guide To
CF</dc:title><dc:creator>J R Luser</dc:creator> ... "
However, I guess the logical end game, using this approach, would be to
put ALL the CF metadata in a single attribute!
char time(record=63, time_len=21);
time:xml_metadata = "<cf:long_name>forecast date and
time</cf:long_name><cf:standard_name>time</cf:standard_name><dc:title>Field Guide To CF</dc:title><dc:creator>J R Luser</dc:creator> ... "
Gulp!!
Regards,
Phil
