I'll investigate further to see if there's a way to silence such issues, as the main purpose is to look for illegal use of HTML elements and attributes, and bad wellformedness.\r\n\r\nIn the mean time, if it can't be easily resolved otherwise, a comment that polyglot markup may be marked in Linter Messages may be all we can do."}}
