Supply Javadoc annotation to specify i18n lookup for Grails tag libraries

Using the build-in grails message taglib - <g:message code="" /> - within the "code" parameter, intellij can autocomplete from i18n property-files.
If using a custom tag library to lookup i18n keys, intellij should supply an annotation to mark the paramater as a i18n property to enable auto completion in custom tags.

It's not possible right now. Please file a feature request at [http://youtrack.jetbrains.com/issues/IDEA](http://youtrack.jetbrains.com/issues/IDEA) and we'll consider adding this feature.

We could add a special JavaDoc tag that will be used to determine that the parameter should be completed as i18n property.

Start with the built-in Grails message tag library and the custom tag-library parameter described in the issue, then review how IntelliJ recognizes i18n keys in the g:message code parameter. Done means a documented Javadoc annotation can mark a custom tag parameter so IntelliJ offers autocomplete from i18n property files.
