A pg:Group MUST have exactly one string lv2:symbol.  This symbol must be
unique according to the same rules as the lv2:symbol for an lv2:Port, where
group symbols and port symbols reside in the same namespace.  In other words,
a group on a plugin MUST NOT have the same symbol as another group or a port
on that plugin.  This makes it possible to uniquely reference a port or group
on a plugin with a single identifier and no context.

A grouping of ports (or any other means of signal transmission) that should
logically be considered a single "stream", e.g. two audio ports in a group may
form a stereo stream.  In order to avoid the need to define large numbers of
identical group definitions, a group definition may be shared.  For example, a
plugin collection may define a single URI for a pg:StereoGroup with the symbol
"input" and use it in many plugins.
