 MapGuide defines a number of functions that can be used in expressions.
 These include:

  * IF
  * LOOKUP
  * RANGE
  * ARGB
  * DECAP
  * URLENCODE
  * FEATURECLASS
  * FEATUREID
  * LAYERID
  * MAPNAME
  * SESSION

 The last four only make sense in the context of MapGuide.  FEATUREID
 returns a utf8-encoded version of the feature ID, LAYERID returns the guid
 of the active layer, MAPNAME is the name of the !MgMap, and SESSION
 returns the session string.  These were originally added to support
 selection of features in the DWF Viewer.

 For applications other than MapGuide, we should provide a way for these
 four functions to be excluded.
