input 

Two input elements are needed to define a
face, one for referencing the surface and
one for referencing the wires themselfs. The
third is needed for the orientation of each
wires.

Attributes

QName Type Fixed Default Use Inheritable Annotation
offset uint_type required 
The offset attribute represents the offset into the list of indices.  If two input elements share 
the same offset, they will be indexed the same.  This works as a simple form of compression for the 
list of indices as well as defining the order the inputs should be used in.  Required attribute.
semantic xs:NMTOKEN required 
The semantic attribute is the user-defined meaning of the input connection. Required attribute.
set uint_type optional 
The set attribute indicates which inputs should be grouped together as a single set. This is helpful 
when multiple inputs share the same semantics.
source urifragment_type required 
The source attribute indicates the location of the data source. Required attribute.
