Description

Consider testing for org.xml.sax.ext.Attributes2 and use Attributes2.isSpecified(int) to check if the attribute is really specified or just a default declaration.

With this you can e.g. test if <a shape="rect" > is really set. Test for "http://xml.org/sax/features/use-attributes2" or just use "instanceof":

if (attributes instanceof Attributes2) {
if (( (Attributes2)attributes ).isSpecified)

{ // do something }

}
