no

can't hurt, though in this case: probably not needed per se, since legal geoSystem values are found in the X3D XML Schema as <xs:simpleType name="geoSystemValues"> and in the Object Model for X3D (OM4X3D) as <SimpleType name="geoSystemValues">

note that enumeration lists like this may be optional or strict, depending on spec requirements for allowed values in a field.

Anyway when not listed in schema, we can further start collecting and documenting regular expressions on this preliminary-draft page:

	X3D Regular Expressions (regexes)
	http://www.web3d.org/specifications/X3dRegularExpressions.html

all the best, Don
