title: Is there a way for the GWT Maven Plugin to generate I18N message interfaces which return SafeHtml?
body: <p>For a GWT project, if you configure the pom to generate your I18N Message bundles, the generated interfaces all return String.</p>
  
  <p>I was wondering if there was a way to have the Message bundle interfaces generated s.t. some or all of the methods return SafeHtml.</p>
  
  <p>I'm not sure how you would selectively decide which messages return String and which return SafeHtml (perhaps through some kind of markup in the .properties file).</p>
