The manual hints towards why:
"According to the DOM standard this requires a DTD which defines the attribute
ID to be of type ID. You need to validate your document with
DOMDocument->validate() or DOMDocument->validateOnParse before using this
function."
You've set validateOnParse, but you haven't posted the contents of abc.xml.
Does it include a DTD that defines ID?
There is a link in the user contributed notes to the following site that
