OK.

I'm working on that but I haven't found useful information. A "how to document"
will be appreciated.

I just follow the AsGML way of a third parameter for future changes on next
versions of KML specs. However, geometry in kml involves three aditional values
related to how GE displays 3D data: extrude,tessellate and altitudeMode. That
third (and eventually a fourth parameter) can be used to define the behaviour
when 3dz or 3dm geometry is passed. All suggestions are welcomed.

AsUKML is the primary function that returns the KML "untransformed". As Google
Earth only understand WGS84 data (srid=4326), I don't know if somebody will
find it useful. What do you think?
