WMS 1.3.2 is not an official OGC specification, but is meant to be used in an interoperable way as the next unofficial WMS version to aid in the evolution of the WMS specifications. This specific version was developed as part of the OWS-4 GeoDSS Multilingual project. Differences between WMS 1.3.1 and WMS 1.3.2: - WMS 1.3.2 uses the DescriptionType XML schema type of OWS Common 1.1.0 as a container for titles, abstracts and keywords. Such DescriptionType objects allow a capabilities document to report descriptions in a multilingual manner. - WMS 1.3.2 accepts an optional LANGUAGE CGI parameter on all requests. This parameter allows the client to indicate to the server what the client's preferred language is. It is a comma-separated list of RFC 4646 language codes in order of client preference. The server should serve its data in the most preferred language it has available for each text string. If the server can't serve any of the preferred languages, it may serve a default language of the server's choice. A special value of "MUL" may be accepted for GetCapabilities requests, indicating that descriptions should be returned in all available languages. If a LANGUAGE parameter is not present in a request, it is recommended that the server attempt to honor the HTTP_ACCEPT_LANGUAGES environment variable (part of the standard HTTP mechanism, and read from the MIME headers of the HTTP request) instead. - WMS 1.3.2 includes a Languages element in the capabilities document, providing a way for catalog servers to categorize WMS servers by which languages they can serve their data in. However, this is informational only, and should not be used to negotiate what languages are requested using the LANGUAGE CGI parameter. - WMS 1.3.2 uses the OWS 1.1.0 ExceptionReport, which can report the language of the text of the exception.
