package com.sun.xml.internal.org.jvnet.fastinfoset.sax;

import org.xml.sax.Attributes;



Interface for a list of XML attributes that may contain encoding algorithm
data.

 Implementations shall ensure that the Attributes.getValue(int) method correctly returns a String object even if the attribute is represented as algorithm data. 
 If an attribute has algorithm data then the getAlgorithmData method shall return a non null value.
