For documents without DTDs, this is probably the only option (any attribute is potentially an #IMPLIED attribute). For documents with DTDs, I could create a query method like boolean isDeclaredAttribute (String elname, String aname) but Ælfred has already grown too large (it's over 25K), so I would need evidence of a pressing need. In the meantime, you can use the query method Enumeration declaredAttributes (String elname, String aname) to build a hashtable, and then look in the hashtable whenever you need to know whether an attribute is #IMPLIED or simply undeclared.
