It is clearly illegal since in section 2.1 it says: "By default, all of
these new types, just like the types from HTML4, must have no value
selected, unless a default value is provided using the value attribute."

Perhaps we need feedback from implementers whether is possible to design a
usable slider control with an "undefined" state. If not, either an
explicit value could be required for range fields, or it could be allowed
for range controls to choose a default value. The last option is probably
best, since implementations would have to handle missing values somehow
anyway, whether they are illegal or not.
