OK.  First thing is, "]" doesn't end "statements" in C like languages, so
some ad hoc stuff will be needed.

Just as a quick test, please try putting a ";" on the line like this:

  [Attribute] ;

, and see whether that fixes the indentation.  I think it should.

If so, I would suggest writing a routine which would detect a "virtual
semicolon" at the end of an "[Attribute]" construct.  The "virtual
semicolon" mechanism is explained in cc-defs.el starting at about line
745.

You'd have to write a vala-mode function for c-at-vsemi-p-fn, and
possibly one for c-vsemi-status-unknown-p-fn, two language specific
variables in cc-langs.el.  The functions for AWK Mode should serve as an
example.

No problem!  Get back to me if you need any more!
