The new text is:

Indicates that resources external to the current document are required. 
If an external resource is not available (for example the request for 
the required resource times out), progressive rendering is suspended, 
the document's load event is not fired and the document goes into an 
error state (see Error processing). The document remains in an error 
state until all required resources become available.

Thank you for your thorough review.  Please let us know shortly if  
this does not address your concerns.
