				  e491. Getting an Attribute's Schema from the Directory
				
				This example reads an attribute's schema from the directory.
				
				
				    try {
				        // Get an attribute of that type
				        Attributes attrs = ctx.getAttributes("cn=Ted Geisel, ou=People", new String[]{"cn"});
				        Attribute cnAttr = attrs.get("cn");
				    
				        // Get its attribute definition
				        DirContext cnSchema = cnAttr.getAttributeDefinition();
				    
				        // Get cnSchema's attributes
				        Attributes cnAttrs = cnSchema.getAttributes("");
				    } catch (NamingException e) {
				    }
