TYPENAME O
A comma separated list of feature types to
describe. If no value is specified that is to be
interpreted as all feature types.
OUTPUTFORMAT O
textxml; subtype=gml3.1.1 The output format to use
to describe feature types. textxml;
subtype=gml3.1.1 must be supported. Other
output formats, such as DTD are possible.
14.7.2.2 Examples Example 1
The following example requests the schema description of the feature type TreesA_1M.

TYPENAME=TreesA_1M
Example 2
The following example requests the schema description of the feature types InWaterA_1M and BuiltUpA_1M.

OUTPUTFORMAT O textxml;

RESULTTYPE O
results The resulttype parameter is used to indicate
whether a WFS should generate a complete response document of whether it should
generate an empty response document indicating only the number of features that
the query would return. A value of results indicates that a full response should be
generated. A value of hits indicates that only a count of the number of features
should be returned.
PROPERTYNAME O
A list of properties may be specified for each feature type that is being queried.
Refer to subclause 14.2.2 on how to form lists of parameters. A character can be
used to indicate that all properties should be retrieved. There is a 1:1 mapping
between each element in a FEATUREID or TYPENAME list and the
PROPERTYNAME list. The absense of a value also indicates that all properties
should be fetched.
FEATUREVERSION= [ALL | N]
O If versioning is supported, the
FEATUREVERSION parameter directs the WFS on which feature version to fetch.. A
value of ALL indicates to fetch all versions of a feature. An integer value fetches the
Nth version of a feature. No value indicates that the latest version of the
feature should be fetched.
MAXFEATURES=N O
A positive integer indicating the maximum number of features that the WFS should
return in response to a query. If no value is specified then all result instances should be
presented.
EXPIRY=N O
This parameter may only be specified if the request is GetFeatureWithLock. It
indicates the length of time in minutes that a lock will be held on the features in
the result set. If the parameter is not specified then the locks will be held
indefinitely.
SRSNAME O
This parameter is used to specify a WFS- supported SRS that should be used for
returned feature geometries. The value may be the DefaultSRS or any of the
OtherSRS values that a WFS declares it supports in the capabilities document. The
SRS may be indicated using EPSG codes or the URL form defined in [2]. If the
parameter is not specified then the value of the DefaultSRS for the feature type being
queried shall be used.
TYPENAME Optional if FEATUREID is
specified. M
A list of feature type names to query.
