Erm, 30.2 uses <names> throughout (note the plural) and then says:
"The attribute <names> parameter normally consists of a single
attribute name but it can be any one of the following:
A single attribute name which evaluates to the attributes value.
Multiple , separated attribute names which evaluates to an empty
string if one or more of the attributes is defined, otherwise it’s
value is undefined.
Multiple + separated attribute names which evaluates to an empty
string if all of the attributes are defined, otherwise it’s value is
undefined.
Conditional attributes with single attribute names are evaluated first
so they can be used inside the multi-attribute conditional<value>."
So I'm not sure where you are quoting :)

My quick googling says the img tag has to refer to the map with a
usemap=#name attribute. Thats something that a normal img block
doesn't do.
You need to define your own image block that does that and is set as
the template of the filter style, then you can use the | to locate the
output of the program where you want it.
I suggest you start with a minimal example and build up, rather than
trying to copy the standard image-block which does stuff like embedded
URIs and so on as well. And the standard graphviz filter which does
svg stuff and so has a variable template value is again more than you
initially need. Look at the code filter example, than add your own
template block so you can position the filter output and can add the
extra attribute you need.
