It is a good bet that all the parsers are doing what I have done in my
parsers: used a single instance of an AttributeList object, then cleared it
and reused it for each call to startElement. Thus, all the references in
your Vector point to the same object.
This is specifically allowed by the SAX spec. The documentation for
AttributeList states, "The instance provided will return valid results only
during the scope of the startElement invocation (to save it for future use,
the application must make a copy: the AttributeListImpl helper class
provides a convenient constructor for doing so)."
