/**
* @class ACEXML_Attributes
*
* @brief ACEXML_Attributes defines a collection of attributes of an XML element.
*
* This is an abstract class (interface in Java) that defines
* the API for accessing attributes of an XML entity.
*
* This interface allows access to a list of attributes in three different ways:
*
* - by attribute index;
* - by Namespace-qualified name; or
* - by qualified (prefixed) name.
*
* The list will not contain attributes that were declared #IMPLIED
* but not specified in the start tag. It will also not contain
* attributes used as Namespace declarations (xmlns*) unless the
* http://xml.org/sax/features/namespace-prefixes feature is set to
* true (it is false by default).
*
* If the namespace-prefixes feature (see above) is false, access by
* qualified name may not be available; if the
* http://xml.org/sax/features/namespaces feature is false, access by
* Namespace-qualified names may not be available.
*
* This interface replaces the now-deprecated SAX1 AttributeList
* interface, which does not contain Namespace support. In addition to
* Namespace support, it adds the getIndex methods (below).
*
* The order of attributes in the list is unspecified, and will vary
* from implementation to implementation.
