it seems that a loose definition of PCDATA and CDATA is that
but then someone told me that CDATA is actually parsed or PCDATA is actually not parsed... so it is a bit of a confusion. Does anyone know the real deal is?
Update: I actually added the PCDATA definition on Wikipedia... so don't take that answer too seriously as that's only my rough understanding of it.

CDATA means the element contains character data that is not supposed to be parsed by a parser. #PCDATA means that the element contains data that IS going to be parsed by a parser. The keyword ANY declares an element with any content. If a #PCDATA section contains elements, these elements must also be declared.
PCDATA. PCDATA means parsed character data. Think of character data as the text found between the start tag and the end tag of an XML element. PCDATA is text that WILL be parsed by a parser.
The term CDATA, meaning character data, is used for distinct, but related, purposes in the markup languages SGML and XML. The term indicates that a certain portion of the document is general character data, rather than non-character data or character data with a more specific, limited structure.
CDATA is defined as blocks of text that are not parsed by the parser, but are otherwise recognized as markup. The predefined entities such as <, >, and & require typing and are generally difficult to read in the markup. In such cases, CDATA section can be used.
From WIKI:
PCDATA
Simply speaking, PCDATA stands for Parsed Character Data. That means the characters are to be parsed by the XML, XHTML, or HTML parser. (
<will be changed to <,<p>will be taken to mean a paragraph tag, etc). Compare that with CDATA, where the characters are not to be parsed by the XML, XHTML, or HTML parser.
