["Greg FitzPatrick" <greg.fitzpatrick@xxxxxxxxxxxxx>]

So I guess we were trying to describe the ultimate polymath:-)

Thanks for the correction - we will get to that right away.

As written, a Personroleparam can only have the value
DIPROLE=<any
text>PERFORMERCREATORCOMPOSERCONDUCTORARTISTEDITORPRODUCERGUIDESPEAKERCHAIRP
RESENTREFERENCEDINVITED,
which is probably not what was intended.

If you want the examples to be examples, put a semicolon to the left of
them.
If you don't, they are part of the grammar - and putting items one after
the other means that they are concatenated, not that they are alternatives.
