The following support is available for the validate:1.1 capability:
The validate:1.1 and 1.0 capabilities are advertised in the NETCONF server <hello> as the following:
<capability>urn:ietf:params:netconf:capability:validate:1.0</capability>
<capability>urn:ietf:params:netconf:capability:validate:1.1</capability>
The <validate> request is supported for an XML content layer request, but not for a CLI content layer request. Detection of a <config-format-cli-block> or <oper-data-format-cli-block> tag in a <validate> request results in an "operation not supported" error response.
A <validate> operation is supported for a selection of config (<source><config>), or for the <running> datastore, which only returns 'OK'. The <validate> operation is not supported for URL sources or the <startup> datastore.
