<complexType name="DirectPositionType">
<annotation>
<documentation>DirectPosition instances hold the coordinates for a position within some coordinate reference system (CRS). Since DirectPositions, as data types, will often be included in larger objects (such as geometry elements) that have references to CRS, the "srsName" attribute will in general be missing, if this particular DirectPosition is included in a larger element with such a reference to a CRS. In this case, the CRS is implicitly assumed to take on the value of the containing object's CRS.</documentation>

<extension base="gml:doubleList">
<attribute name="srsName" type="anyURI" use="optional">
<annotation>
<documentation>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 (Note: These "WKCRS"-ids still have to be specified). 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 the attribute will be specified at the direct position level only in rare cases.</documentation>

<attribute name="dimension" type="positiveInteger" use="optional">
<annotation>
<documentation>The attribute "dimension" is the length of coordinate sequence (the number of entries in the list). This is determined by the coordinate reference system.</documentation>
