I just tried your suggestion. It seems to create a new <defs> tag that
gets appended to the uppermost <g> tag. This isn't exactly what I had
in mind (I wanted access to the uppermost <defs> tag) but it seems to
work ok for my needs. This allows me to insert a piece of javascript
once per document rather than inserting it redundantly into each new <g>
tag.
Thanks for your help.
