java.lang.Object | +--org.apache.xerces.util.XMLAttributesImpl
The XMLAttributesImpl class is an implementation of the XMLAttributes interface which defines a collection of attributes for an element. In the parser, the document source would scan the entire start element and collect the attributes. The attributes are communicated to the document handler in the startElement method.
The attributes are read-write so that subsequent stages in the document pipeline can modify the values or change the attributes that are propogated to the next stage.

public java.lang.String getType(int index)
The attribute type is one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", or "NOTATION" (always in upper case).
If the parser has not read a declaration for the attribute, or if the parser does not report attribute types, then it must return the value "CDATA" as stated in the XML 1.0 Recommentation (clause 3.3.3, "Attribute-Value Normalization").
For an enumerated attribute that is not a notation, the parser will report the type as "NMTOKEN".

The names must be unique: the SAX parser shall not include the same attribute twice. Attributes without values (those declared #IMPLIED without a value specified in the start tag) will be omitted from the list.
If the attribute name has a namespace prefix, the prefix will still be attached.
