-  keywords. Such attributes are called <dfn id=enumerated-attribute title="enumerated
-  attribute">enumerated attributes</dfn>. The keywords are each
-  defined to map to a particular <em>state</em> (several keywords
-  might map to the same state, in which case some of the keywords are
-  synonyms of each other; additionally, some of the keywords can be
-  said to be non-conforming, and are only in the specification for
-  historical reasons). In addition, two default states can be
-  given. The first is the <i>invalid value default</i>, the second
-  is the <i>missing value default</i>.<p>If an enumerated attribute is specified, the attribute's value
-  must be an <a href=#ascii-case-insensitive>ASCII case-insensitive</a> match for one of the
-  given keywords that are not said to be non-conforming, with no
-  leading or trailing whitespace.<p>When the attribute is specified, if its value is an <span>ASCII
-  case-insensitively</span> match for one of the given keywords then
-  that keyword's state is the state that the attribute represents. If
-  the attribute value matches none of the given keywords, but the
-  attribute has an <i>invalid value default</i>, then the attribute
-  represents that state. Otherwise, if the attribute value matches
-  none of the keywords but there is a <i>missing value default</i>
-  state defined, then <em>that</em> is the state represented by the
-  attribute. Otherwise, there is no default, and invalid values must
-  be ignored.<p>When the attribute is <em>not</em> specified, if there is a
-  <i>missing value default</i> state defined, then that is the state
-  represented by the (missing) attribute. Otherwise, the absence of
-  the attribute means that there is no state represented.<p class=note>The empty string can be one of the keywords in some
-  cases. For example the <code title=attr-contenteditable><a href=#attr-contenteditable>contenteditable</a></code> attribute has
-  two states: <i>true</i>, matching the <code title="">true</code>
-  keyword and the empty string, <i>false</i>, matching <code title="">false</code> and all other keywords (it's the <i>invalid
-  value default</i>). It could further be thought of as having a
-  third state <i>inherit</i>, which would be the default when the
-  attribute is not specified at all (the <i>missing value
-  default</i>), but for various reasons that isn't the way this
-  specification actually defines it.<h4 id=syntax-references><span class=secno>2.4.9 </span>References</h4><p>A <dfn id=valid-hash-name-reference>valid hash-name reference</dfn> to an element of type <var title="">type</var> is a string consisting of a U+0023 NUMBER SIGN
