Subject: RE: [emergency] Re: Circle and Polygon
If the reference system is considered a identified form of measurement or a distinct qualifier it should be an attribute. It is metadata describing a specific quality or context of the element. In order to do this you must make a reference system element its own separate base type. It can not belong in the realm of type text or type code. The reason is metadata attributes should be connected to the type and not just to an element name (reuse). It is not good practice to have single elements with their on special metadata attributes.

I personally prefer using an attribute, but I would be o.k. with an element that indicates the spatial reference system as a sub-element of <polygon> and <circle>.

We've stayed clear of attributes for various reasons, but would it achieve the same end to name the elements something like <wgs84polygon> and <wgs84circle>? - Art --------------------------------------------------------------------- To unsubscribe from this mail list, you must leave the OASIS TC that generates this mail.
