Here's a snippet of what these mean.   This info is not in the OGC:WMS
specification, but the OGC:SLD specification (section 6.7 from
https://portal.opengeospatial.org/files/?artifact_id=1188):

<!ELEMENT UserDefinedSymbolization (SupportedSLDVersion*)>
<!ATTLIST UserDefinedSymbolization

<!-- If the WMS supports a StyledLayerDescriptor (SLD) then the
SLD parameter can be used in place of LAYERS and STYLES
parameters in a GetMap request. -->
SupportSLD (0 | 1) "0"

<!-- If the WMS supports UserLayers then users can define their
own layers in the SLD in addition to NamedLayers already known to
the WMS. -->
UserLayer (0 | 1) "0"

<!-- If the WMS supports UserStyles then users can define their
own styles in the SLD to be applied to previously specified
layers. -->
UserStyle (0 | 1) "0"

<!-- If the WMS supports remote WFS or WCS then a remote service
can be specified as the source of features to be symbolized. -->

RemoteWFS (0 | 1) "0"

RemoteWCS (0 | 1) "0">

<!-- Indication of what SLD version(s) are supported by a WMS -->
<!ELEMENT SupportedSLDVersion (#PCDATA)>
