Yes and no.  <newline/> is not needed in XML.  ISO10646 includes 
characters which  unambigously represent line-breaks and paragraph breaks: 
U+2028 and U+2029.

<foo>I am data 1&#x2028;I am data 2</foo>

Any conventions for handling whitespace in XML do not need to address
"hard returns".  If someone wants a hard return, they can mark it up
explicitly just using what XML already provides (by adopting ISO 10646).

Similarly, XML-DEV does not need to make up any conventions to handle 
no-break spaces (&nbsp; or &#x00A0;) or "hard spaces" (ideographic space 
does not collapse: &#x3000;).

Lets not make this more complicated than it is!

P.S. In the example quoted, I think probably <RCDATA> is a closer
description of the element rather than <PCDATA>.
