Hi,

the TimePeriod element requires the gml:id attribute with some formatted
content to actually pass the validation. I put gml:id="ID001" in the
above sample and that does the job. Sorry for my ignorance, but why
is this supposed to be there? What is the idea behind the identifier
and could I just put anything I wanted in there?
As far as I've understood, there is a basic principle in GML saying that every object
has to be given an identifier.
There is at the GML level no rule specifying what to put in the identifier. This should be
done at a higher level. For instance in Europe, INSPIRE draft documents recommend to use a
namespace-based syntax.
Hope this helps,
Robert
PS Congratulations for new GN release. Really nice work.
