No. This applies to boolean attributes only.
A very small number of HTML-attributes (approx 5?) can take values in form
of boolean variables. These values are interpreted as "true" when the
attribute is present or "false" when the attribute is absent, e.g.
<!ATLIST OPTION
selected (selected) #IMPLIED >
Boolean attribute can take one single value - itself. The name of
attribute type and value type are the same.
<option selected="selected">
As the presence of the attribute alone imples the value to be "true", the
value can be omitted - minimized.
<option selected>
