..another email that slipped through in my Xmas email storm...
Bruce, did you get a reply from anyone on this? I don't recall any decision on this at Rome. We talked about borehole surveys vs gml:curve, but not about your question as I recall.
Having said that, I think your proposal is to change the data type is correct. I'm not sure why we modelled CoredInterval as gml:Envelope. Is there a member of the Boreholes subgroup (from circa Melbourne 2007) that can tell us the reason why gml:Envelope was used (or if it is just an error).

Subject: [auscope-geosciml] Borehole gsml:coredInterval GM_Envelope vs GM_Object
The discussion on the TWiki on GM_Envelope vs GM_Object for gsml:coredInterval has:
"For sa:shape and gsml:shape we have used GM_Object, which allows the use of gml:LineString. For gsml:coredInterval we have used GM_Envelope which allows gml:Envelope. gml:LineString allows gml:id as well as srsName, whereas gml:Envelope doesn't allow gml:id. This precludes referring to the same geometries described in the Observations (see "Multiple Properties" discussion above).
More importantly it requires gml:lowerCorner and gml:upperCorner, rather than the two gml:pos values gml:LineString uses. This is inconsistent and wrong, the gsml:coredInterval should be treated the same as the Observation interval."
My recollection from Rome was we decided to change the data type on coredInterval. Is this correct?
