See spec section 4.4.5 Conditional Component Declaration
"If the Boolean expression is false the component is not present in the
flattened DAE [its modifier is ignored], and connections to/from the
component are removed."

This seems broken to me. Shouldn't there be if-equations around the
connect equations? Either "support" or "fixed" is going to be missing.
Won't that raise errors? How is OpenModelica OK with this?
