Structurally, the XML is simpler in the status quo, right?
And the status quo avoids overloading the term "context",
which elsewhere means "the sets of visible input ports,
output ports, and parameters", with the meaning "the sole
input port".

So unless someone can explain to me in terms I understand
why we should prefer 2, I'm for the status quo.
