doclint: structural issue hidden

/** <p id= > empty value </a> */

Should generate, something like:
Test.java:13: error: invalid name for anchor: ""
     * <p id= > empty value </a>
           ^
Test.java:13: error: unexpected end tag: </a>
     * <p id= > empty value </a>
                                        ^

Instead it generates:
Test.java:13: error: invalid name for anchor: ""
     * <p id= > empty value </a>
            ^

Note: the implementation assumes illegal attributes are always for an anchor, so
the message is as implemented, but not necessarily the most descriptive.



/** <p> no end required </a> */

Should generate:
Test.java:14: error: unexpected end tag: </a>
     * <p> no end required </a>
                                      ^

But goes undetected. The endtag appears to be associated to the preceding
tag for which no end-tag is required.


/** <p> end allowed </p> </a> */

Correctly generates:
Test.java:15: error: unexpected end tag: </a>
     * <p> no end required </p></a>
                                           ^
