-All coordinate values must fall within the minimal range of values appropriate for the 
-coordinate system in use. For example, equatorial coordinate limits are [0,360) for longitude 
-and [-90,90] for latitude; other coordinate systems may define different limits.
+Coordinate values are not limited to fall within a defined valid range; this is a change from
+the previous version where equatorial coordinates were explicitly limited. Software may have
+to perform range reduction in some coordinate systems (for example, spherical coordinates) in 
+order to correctly interpret or use the coordinate values. Coordinate values are more likely to
+work as expected if they are expressed in the simplest form and do not require range reduction.
+For example, in spherical coordinates, \verb\362.0 2.0| is equivalent to \verb|2.0 2.0|, but the
+latter form is more likely to work as intended in all cases.
 
 There is no general purpose definition of minimum and/or maximum point values, but
 specific services may define something that is applicable in a more limited context.
 
 \subsection{Circle}
 Circle values serialised in VOTable or service parameters must have the following metadata in the
 \xmlel{FIELD} element: \verb|datatype="double"| or \verb|datatype="float"|, \verb|arraysize="3"|,
-\verb|xtype="circle"|. For circles
-in a spherical coordinate system, the values are ordered as: longitude latitude
-radius; longitude values must fall within [0,360], latitude values
-within [-90,90], and radius values in (0,180]. For example:
+\verb|xtype="circle"|. 
+The values are ordered as a point followed by a radius. For example:
