WFS GetFeatures with OGC Filters not working with Custom OutputFormats

[chodgson]

Some OGC filters cause empty result sets to be returned when used in combination with maxfeatures and using a custom output format.

Here is an example URL:

http://localhost/cgi-bin/ms6/mapserv.exe
?map=h:\mapfiles\test\test.map
&service=WFS
&version=1.0.0
&request=GetFeature
&TypeName=holypoly
&SRS=EPSG:4326
&MAXFEATURES=200
&OUTPUTFORMAT=foo
&FILTER=<ogc:Filter xmlns:gml="http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc"><ogc:PropertyIsBetween><ogc:PropertyName>NAME</ogc:PropertyName><ogc:LowerBoundary><ogc:Literal>b</ogc:Literal></ogc:LowerBoundary><ogc:UpperBoundary><ogc:Literal>d</ogc:Literal></ogc:UpperBoundary></ogc:PropertyIsBetween></ogc:Filter>

This URL returns an empty set of data using my custom outputformat "foo" (which is a custom KML format). If I remove the "MaxFeatures" parameter, it returns the correct result, or alternatively if I do not specify an outputformat, it returns me the correct results in the default GML format.

Filter operators which I have to tested that fail in this case (return empty results when there are known results matching the filter):

<And>
<Or>
<propertyIsBetween>
<PropertyIsEqualTo>

However these others work correctly:

<PropertyIsLessThan>
<PropertyIsGreaterThan>

While removing the maxfeatures is a potential workaround, this is not ideal as the maxfeatures parameter is handy to prevent overloading the server.

Note that my the custom outputformat "foo" is a template-driven outputformat, defined like this in the mapfile:

  OUTPUTFORMAT
    NAME 'foo'
    DRIVER TEMPLATE
    MIMETYPE 'application/vnd.google-earth.kml+xml'
    #MIMETYPE 'text/kml'
    FORMATOPTION 'FILE=test2.kml'
    FORMATOPTION 'ATTACHMENT=gmap_getfeatureinfo.kml'
  END

FYI, I tested the patch for #4011 and it had no effect on this issue.
