Poor deprecation notice for using classBinding in a template.

[rwjblue]

DEPRECATION: You're using legacy class binding syntax: classBinding=":input type socialMediaValidClass" @ 4:60 in (inline). Please replace with class=""

Needs to include moduleName and line number if possible, along with the corrected syntax.

How I can get rid of classBinding deprecation in this case?

{{input classBinding=":validate errors:invalid"}}
