[pstricks] About the dimen of closed and open curves

Dear folks,

I am still confused with the convention adopted in PSTricks for closed and open curves.

The default value of dimen of closed curves:
\pscircle outer
\psellipse outer
\psframe outer

\pspolygon middle
\pswedge middle

The default value of dimen of open curvers:

\psline middle
\psplot middle
\pscurve middle
\psbezier middle
\psarc middle

\psellipticarc  outer


1. Why are the dimen of \pspolygon and \pswedge set to middle instead of outer? 
2. Why is the dimen of \psellipticarc set to outer instead of middle?

Thank you.
