I don't think that argument works in general. For example: in CSS, if you have
"display: none" then your choice of font is moot, since you won't be rendering
any text. But that doesn't mean that choice of font should be controlled by the
"display" property, nor should display type be determined by font-face. To give
another example, when the type attribute of the "input" element is "image",
then the "src" attribute specifies the image to load. For other values of the
type attribute it has no effect. Likewise the "multiple" attribute only applies
for a subset of values of the "type" attribute. Yet it would not be the best
design to make the choice of image, or the choice of multiple vs not, be part
of the value of the type attribute.

It's not unexpected that attributes would sometimes interact, and that that not
all possible combinations may make sense. I think it's only logical to combine
things when they are truly affecting the same behavior. But "how much to load"
and "whether to start playing automatically" are separate behaviors, even
though they are contingent.
