Stroked textpath with underline, overline and strikethrough attributes

Hi,

After discussion, here are the screenshots of what
we get with stroked textpath with underline, overline 
and strikethrough attributes.

The result is not really nice but is it what the WG
expected ?

The first screenshot simply shows
the same rendering problem with a text element 
and a tspan with dx and dy attributes.

Any comments ?
Thierry
