GetFeatureInfo and text/plain, no attributes shown

[Daniel Morissette]

Bart, Assefa,

FYI I just added the following notes to the MIGRATION_GUIDE.TXT (in 4.10 
CVS):

WMS GetFeatureInfo in text/plain format
---------------------------------------

Before MapServer 4.10, WMS GetFeatureInfo output in text/plain format
used to always return the values of *all* attributes for the selected
shapes in a given layer and there was no way to control which attributes
would be returned. This was a problem for WMS server administrators who
needed to control the list of attributes to return or to hide some
attributes from the underlying dataset.

Starting with MapServer 4.10, the behavior of text/plain GetFeatureInfo
output has been brought in sync with that of GML output: by default
no attributes are returned unless the wms_include_items and
wms_exclude_items layer-level metadata are used. (See bug 1761)

For more details see the gml_include_items and gml_exclude_items layer
object metadata docs in the WMS Server HOWTO at
http://mapserver.gis.umn.edu/docs/howto/wms_server/#layer-object-metadata

The GML output is controlled with gml_include_items and gml_exclude_items.
The text/plain output is controlled with wms_include_items and
wms_exclude_items.
Both GML and text/plain can also be configured using a common pair of
ows_include_items and ows_exclude_items layer-level metadata entries.

OGC Web Feature Service (WFS)
----------------------------------------------------


Requirement for gml_featureid
-----------------------------

The WFS 1.0.0 specification states that the 'fid' attribute on GML features
returned in response to a GetFeature is required (see bug 1759).

Since MapServer 4.8 it was already possible to specify the attribute to
use as fid using the "gml_featureid" metadata, but that was not a 
requirement.

MapServer 4.10 has been modified to produce a warning in the GetCapabilities
and GetFeature output if the gml_featureid metadata is not set or if the
item that it refers to does not exist in the layer (see bugs 1781 and 1782).
