SVG output - Group multiple grobs together

[James Opstad]

Hello,

I have been experimenting with the new output-attributes grob property for SVG output. For example, the following code creates a group with id="noteC" around the C notehead.

\version "2.19.80"

\pointAndClickOff

\relative c' {

  \once \override NoteHead.output-attributes = #'((id . noteC))

  c4 d e f |

}

How would I include multiple grobs within the same group e.g. all the grobs associated with a single note (NoteHead, Stem, Accidental etc.)?

Thanks,

James
