Legal, yes, but probably not what you want. A field can be listed more 
than once iff it's possible to list it exactly once with all the values 
comma delimited.

So the above is legal if the following is. And the above would be treated 
as the follow by compliant systems.

<META HTTP-EQUIV="Subject.scheme"
		CONTENT="Dewey Decimal System, Some other system">
<META HTTP-EQUIV="Subject"
		CONTENT="004.64, Model Trains">

Servers will generally ignore your NAME attribute (which won't do much 
good as that's where you want the information for robots, etc.)

Why not just:

<META HTTP-EQUIV="DDS" CONTENT="004.64">
<META HTTP-EQUIV="SOS" CONTENT="Model Trains">

?

Is there something significant about starting with "Subject" that I don't 
know about? (quite likely :-)
