Which is… a lot of code. It also means that you can not specify different markers with different repeatings in different contexts, you are always bound to one pattern, and can't specify independent patterns as well, or need to continue listing the urls until the frequencies of the two different patterns come together. Just see the following two patterns as example:

No, you didn't read my grammar correctly, nor my additional
explanations where I said that the ability to set up independent
marker tracks seems useful.  In my proposal, you'd write it as:

marker-pattern: url(#m1) 20px, url(#m2) 9px;

If you think that looks exactly like yours (except there's a comma
separating the separate marker tracks), you're right!  I think my
proposal mixes the best of your proposal and the current grammar.  It
lets you mix multiple markers in a single track, *and* it lets you do
independent tracks.
