Hi,
WMS standard does not mandate any info format. Only one that is fixed is the service exception format which is "XML" by default in WMS 1.3.0. Standard only says that the supported formats must be advertised. Nothing prevents disabling GML as far as I understand .
>From WMS 1.3.0 standard:
7.4.3.5 INFO_FORMAT
The mandatory INFO_FORMAT parameter indicates what format to use when returning the feature information.
Supported values for a GetFeatureInfo request on a WMS server are listed as MIME types in one or more
<Request><FeatureInfo><Format> elements of its service metadata. The entire MIME type string in <Format> is
used as the value of the INFO_FORMAT parameter. In an HTTP environment, the MIME type shall be set on the
returned object using the Content-type entity header. If the request specifies a format not supported by the server,
the server shall issue a service exception (code = InvalidFormat).
EXAMPLE The parameter INFO_FORMAT=text/xml requests that the feature information be formatted in XML.
