Annotations
Stoplines are lines where the local
continuity or regularity of the surface is questionable.
In the area of these pathologies, triangles intersecting
a stopline shall be removed from the tin surface, leaving
holes in the surface. If coincidence occurs on surface
boundary triangles, the result shall be a change of the 
surface boundary. Stoplines contains all these
pathological segments as a set of line strings.

Annotations
Breaklines are lines of a critical
nature to the shape of the surface, representing local
ridges, or depressions (such as drainage lines) in the
surface. As such their constituent segments must be
included in the tin eve if doing so
violates the Delauny criterion. Break lines contains these
critical segments as a set of line strings.

Annotations
Areas of the surface where data is not 
sufficiently dense to assure reasonable calculation shall be    
removed by adding a retention criterion for triangles based 
on the length of their sides. For many triangle sides  
exceeding maximum length, the adjacent triangles to that 
triangle side shall be removed from the surface.

Annotations
The corners of the triangles in the TIN 
are often referred to as pots. ControlPoint shall contain a 
set of the GM_Position used as posts for this TIN. Since each  
TIN contains triangles, there must be at least 3 posts. The 
     order in which these points are given does not affect the 
     surface that is represented. Application schemas may add 
     information based on ordering of control points to facilitate 
     the reconstruction of the TIN from the control points.

Annotations
A tin is a triangulated surface that uses
the Delauny algorithm or a similar algorithm complemented with
consideration of breaklines, stoplines, and maximum length of 
triangle sides. These networks satisfy the Delauny's criterion
away from the modifications: Fore each triangle in the 
network, the circle passing through its vertices does not
contain, in its interior, the vertex of any other triangle.

Attributes
QName Type Fixed Default Use Annotation
axisLabels gml:NCNameList optional
Ordered list of labels for all the axes of this CRS. The gml:axisAbbrev value should be used for these axis 
labels, after spaces and forbiddden characters are removed. When the srsName attribute is included, this attribute is optional. 
When the srsName attribute is omitted, this attribute shall also be omitted.
gid string optional
This attribute is included for backward compatibility with GML 2 and is deprecated with GML 3. 
This identifer is superceded by "gml:id" inherited from AbstractGMLType. The attribute "gid" should not be used 
anymore and may be deleted in future versions of GML without further notice.
gml:id ID optional
Database handle for the object.  It is of XML type ID, so is constrained to be unique in the XML document within which it occurs.  An external identifier for the object in the form of a URI may be constructed using standard XML and XPointer methods.  This is done by concatenating the URI for the document, a fragment separator, and the value of the id attribute.
srsDimension positiveInteger optional
The "srsDimension" is the length of coordinate sequence (the number of entries in the list). This dimension is 
specified by the coordinate reference system. When the srsName attribute is omitted, this attribute shall be omitted.
srsName anyURI optional
In general this reference points to a CRS instance of gml:CoordinateReferenceSystemType 
(see coordinateReferenceSystems.xsd). For well known references it is not required that the CRS description exists at the 
location the URI points to. If no srsName attribute is given, the CRS must be specified as part of the larger context this 
geometry element is part of, e.g. a geometric element like point, curve, etc. It is expected that this attribute will be specified 
at the direct position level only in rare cases.
uomLabels gml:NCNameList optional
Ordered list of unit of measure (uom) labels for all the axes of this CRS. The value of the string in the 
gml:catalogSymbol should be used for this uom labels, after spaces and forbiddden characters are removed. When the 
axisLabels attribute is included, this attribute shall also be included. When the axisLabels attribute is omitted, this attribute 
shall also be omitted.
