			<documentation>The method for identifying a temporal position is specific to each temporal reference system.  gml:TimePositionType supports the description of temporal position according to the subtypes described in ISO 19108.
Values based on calendars and clocks use lexical formats that are based on ISO 8601, as described in XML Schema Part 2:2001. A decimal value may be used with coordinate systems such as GPS time or UNIX time. A URI may be used to provide a reference to some era in an ordinal reference system . 
In common with many of the components modelled as data types in the ISO 19100 series of International Standards, the corresponding GML component has simple content. However, the content model gml:TimePositionType is defined in several steps.
Three XML attributes appear on gml:TimePositionType:
A time value shall be associated with a temporal reference system through the frame attribute that provides a URI reference that identifies a description of the reference system. Following ISO 19108, the Gregorian calendar with UTC is the default reference system, but others may also be used. Components for describing temporal reference systems are described in 14.4, but it is not required that the reference system be described in this, as the reference may refer to anything that may be indentified with a URI.  
For time values using a calendar containing more than one era, the (optional) calendarEraName attribute provides the name of the calendar era.  
Inexact temporal positions may be expressed using the optional indeterminatePosition attribute.  This takes a value from an enumeration.</documentation>

			<documentation>gml:NilReasonType defines a content model that allows recording of an explanation for a void value or other exception.
gml:NilReasonType is a union of the following enumerated values:
-	inapplicable there is no value
-	missing the correct value is not readily available to the sender of this data. Furthermore, a correct value may not exist
-	template the value will be available later
-	unknown the correct value is not known to, and not computable by, the sender of this data. However, a correct value probably exists
-	withheld the value is not divulged
-	other:text other brief explanation, where text is a string of two or more characters with no included spaces
and
-	anyURI which should refer to a resource which describes the reason for the exception
A particular community may choose to assign more detailed semantics to the standard values provided. Alternatively, the URI method enables a specific or more complete explanation for the absence of a value to be provided elsewhere and indicated by-reference in an instance document.
gml:NilReasonType is used as a member of a union in a number of simple content types where it is necessary to permit a value from the NilReasonType union as an alternative to the primary type.</documentation>

			<documentation>This type is deprecated for tuples with ordinate values that are numbers.
CoordinatesType is a text string, intended to be used to record an array of tuples or coordinates. 
While it is not possible to enforce the internal structure of the string through schema validation, some optional attributes have been provided in previous versions of GML to support a description of the internal structure. These attributes are deprecated. The attributes were intended to be used as follows:
Decimal	symbol used for a decimal point (default="." a stop or period)
cs        	symbol used to separate components within a tuple or coordinate string (default="," a comma)
ts        	symbol used to separate tuples or coordinate strings (default=" " a space)
Since it is based on the XML Schema string type, CoordinatesType may be used in the construction of tables of tuples or arrays of tuples, including ones that contain mixed text and numeric values.</documentation>
