How about replacing the five with following method and three constants?

public static final int NAME = 0;
public static final int PUBLIC_ID = 1;
public static final int SYSTEM_ID = 2;

public abstract String[] getDataInfo (int index);

Since AttributeList is valid only within startElement method, you can reuse
a single string array rather allocate a new one per getEntityInfo method.
If the method returns null, then it is attribute has no info.

If you haven't guessed by now, the constants above are used to index into
the returned array.  Implementations should take steps to make sure the size
of the returned array is 3 and stuff null for NAME if it is not a notation.

Does this help?
