Is name attribute essential in an attribute

hi all,
	I am an XML newbie and am trying to understand the Schema
documentation. 
In the document http://www.w3.org/TR/xmlschema-1/, "XML Representation
Summary: attribute Element Information Item", the name attribute is not
shown as bold, which should mean it is optional. However the property
description says:
	{name} The ·actual value· of the name [attribute] 
Since .absent. is not allowed , doesn't it mean name is necessary attribute.
	I am confused. Please Help

	Thanks in advance,
Ajay
