David,
I am trying to implement this...
(assuming that "VisualStyleSet" is actually "VisualThemeSet")

if I well understand, with the proposed association, a VisualTheme can be
part of only one VisualThemeSet,

Correct.

a WebSite can use only one VisualThemeSet

Correct.

and so we cannot have a theme
applied to more than one WebSite.

Incorrect. Transitive logic does not apply to one-way relationships (these are one-to-many, not one-to-one).

Any number of themes can be part of a theme set. Any number of web sites can use a theme set.

There is no constraint between themes and web sites, just between themes and theme sets, and web sites and theme sets.
