Seems to me you don't like the verbosity, and are willing to trade
some of the flexibility of the greater verbosity for a shorter
problem.

I personally am not concerned about verbosity too much as long as it
isn't superflous and the Edit mode has a reasonable interface.

This means you would never want to mix a vector/click/line types of
clicking together.

Possibly, but with

<circle>
  <x unit="pixel">250</x>
  <y unit="percentage">30</y>
  <radius>15</radius>
</circle>

more flexbility is maintained.

Which worries me, since my examples aren't really that complex.
