If we start from the one-attribute approach, we can improve the situation
in a simiilar manner to how style is attached to an element.
For example:
<head>
<srcset name="foobar">
some list-of-lists-of-lists-of-lists
</srcset>
</head>
<body>
<img srcset="ref(#foobar)" />
or even
<img src="srcset(foobar)" />
</body>
We can even do this kind of thing after the basic <img
srcset="all-kinds-of-stuff" /> is supported, solving the feature problem
first and the authoring convenience problem second.
