gml:TopoComplex 

gml:TopoComplex is a collection of topological primitives.
Each complex holds a reference to its maximal complex (gml:maximalComplex) and optionally to sub- or super-complexes (gml:subComplex, gml:superComplex). 
A topology complex contains its primitive and sub-complex members.

Attributes

QName Type Fixed Default Use Inheritable Annotation
aggregationType gml:AggregationType optional
gml:id ID required 
The attribute gml:id supports provision of a handle for the XML element representing a GML Object. Its use is mandatory for all GML objects. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs.
isMaximal boolean false optional
