 Changes in WKB (read) behaviour proposal (WKT Part)] discussion on the
 list.

 We should try to add ability to consume/produce the M (measure) component
 from/to geometries encoded in OGC WKT and WKB formats.

 As Barend explained in the thread linked above:

 > We drop the M anyway (currently).
 > We cannot handle it because our Point Concept does not contain model-
 values.
 > Something additional would be necessary to be able to assign
 > it to the point in question (strategy? policy? assigner?),
 > which can do with it what it wants.
 > An easy option would be assigning the M to the third dimension
 > (if any), and that is probably currently the case
 > (I have to check).

 I think a form of user-defined data assigner, similar to dimension
 assigners, which uses can enable for adapted geometries would be useful.
