White Space in Attributes

There are several ways of accessing an attribute value. The IXMLDOMAttribute interface has a nodeValue property, a value property which is equal to nodeValue and a text property which is the Microsoft extension. These properties return the following:

property	text returned
attrNode.nodeValue attrNode.value getAttribute("name")	Returns exact content (with entities expanded) as found in the original document.
attrNode.nodeTypedValue	Null
attrNode.text	Same as nodeValue except the leading and trailing white space is trimmed.

The XML Language specification defines the following behavior for XML Applications:

Attribute type	Text returned
CDATA	ID, IDREF, IDREFS, ENTITY, ENTITIES, NOTATION, enumeration
half normalized	fully normalized

Where half normalized means that newlines and tab characters are converted to spaces, but multiple spaces are not collapsed into one space.
