  <DD>REVISIT: Ian, this is probably the most wfs specific addition. If
       you'd like I can subclass and add it there.  It has to be added

setGmlPrefixing</H3>
<PRE>
public void <B>setGmlPrefixing</B>(boolean&nbsp;prefixGml)</PRE>
<DL>
<DD>If Gml Prefixing is enabled then attributes with names that could be
 prefixed with gml, such as description, pointProperty, and name, will
 be.  So if an attribute called name is encountered, instead of
 prepending the default prefix (say gt2:name), it will turn out as
 gml:name.  Right now this is fairly hacky, as the gml:name,
 gml:description, ect., should be in the first attributes by default.
 The actualy geometry encodings will always be prefixed with the proper
 gml, like gml:coordinates. This only applies to attributes, that could
 also be part of the features normal schema (for example a pointProperty
 could be declared in the gt2  namespace, instead of a gml:pointProperty
 it would be a gt2:pointProperty.
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>prefixGml</CODE> - <tt>true</tt> if prefixing gml should be enabled.
        Default is disabled, no gml prefixing.<DT><B>'TODO:'</B></DT>
  <DD>REVISIT: only prefix name, description, and boundedBy if they
       occur in their proper places.  Right now names always get gml
       prefixed if the gmlPrefixing is on, which is less than ideal., REVISIT: The other approach is to allow for generic mapping, users
       would set which attributes they wanted to have different
       prefixes.</DD>

<A NAME="setFeatureBounding(boolean)"><!-- --></A><H3>
setFeatureBounding</H3>
<PRE>
public void <B>setFeatureBounding</B>(boolean&nbsp;featureBounding)</PRE>
<DL>
<DD>Sets whether a gml:boundedBy element should automatically be generated
 and included.  The element will not be updateable, and is simply
 derived from the geometries present in the feature.
 
 <p>
 Note that the <tt>setGmlPrefixing()</tt> interacts with this
 occasionally, since it will hack in a gml prefix to a boundedBy
 attribute included in the featureType.  If gml prefixing is on, and
 featureBounding is on, then the bounds from the attribute will be used.
 If gml prefixing is off, then that boundedBy attribute will
 presumably be in its own namespace, and so the automatic gml boundedBy
 will not conflict, so both will be printed, with the automatic one
 deriving its bounds from the boundedBy attribute and any other
 geometries in the feature
 </p>
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>featureBounding</CODE> - <tt>true</tt> if the bounds of the feature should
        be automatically calculated and included as a gml:boundedBy in
        the gml output.  Note this puts a good bit of bandwidth overhead
        on the  output.  Default is <tt>false</tt></DL>
