xml - DSpace , using html in hint tag -

<hint>i want 2 line <br> doesn't work.</hint> 

how can add html code in hint tag in input-form.xml / dspace . or can 2 hint? in advance.

(for xmlui) customize describestep class make message hint. instead of inserting html in hint-tag you'd give message key. in message.xml file can add messages contain html.
