MinT is translating PLURAL|GRAMMAR|GENDER syntax which is not desirable:
curl -X 'POST' \ 'https://cxserver.wikimedia.org/v1/mt/en/hi/MinT' \ -H 'accept: application/json' \ -H 'Content-Type: application/json' \ -d '{ "html": "{{PLURAL|one=%{count} report|%{count} reports}}" }' {"contents":"{ ′PLURAL|one=% ′count′ report|% ′Count′ report"}
Additionally the HTML translate (https://html.spec.whatwg.org/multipage/dom.html#the-translate-attribute) attribute also does not seem to be respected.
curl -X 'POST' \ 'https://cxserver.wikimedia.org/v1/mt/en/hi/MinT' \ -H 'accept: application/json' \ -H 'Content-Type: application/json' \ -d '{ "html": "<span translate=\"no\">{{PLURAL</span>|one=%{count} report|%{count} reports}}" }' {"contents":"{ ′PLURAL|one=% ′count′ report|% ′Count′ report"}
