I'm learning DTD external from here....

http://www.w3schools.com/dtd/default.asp

.....but the CDATA #PCDATA thing has got me confused.

Here's the example from the end of the article...

Code:
<!DOCTYPE NEWSPAPER [ <!ELEMENT NEWSPAPER (ARTICLE+)>
<!ELEMENT ARTICLE (HEADLINE,BYLINE,LEAD,BODY,NOTES)>
<!ELEMENT HEADLINE (#PCDATA)>
<!ELEMENT BYLINE (#PCDATA)>
<!ELEMENT LEAD (#PCDATA)>
<!ELEMENT BODY (#PCDATA)>
<!ELEMENT NOTES (#PCDATA)> <!ATTLIST ARTICLE AUTHOR CDATA #REQUIRED>

<!ATTLIST ARTICLE EDITOR CDATA #IMPLIED>
<!ATTLIST ARTICLE DATE CDATA #IMPLIED>
<!ATTLIST ARTICLE EDITION CDATA #IMPLIED>

<!ENTITY NEWSPAPER "Vervet Logic Times">
<!ENTITY PUBLISHER "Vervet Logic Press">
<!ENTITY COPYRIGHT "Copyright 1998 Vervet Logic Press">]>

Why is the "HEADLINE" first declared as #PCDATA and then CDATA?

I was wanting to use CDATA in case someone inputs a "<" into a form.

Thanks in advance.

EDIT: found out what this one was, the dtd wasn't valid so was being ignored

And, er, while I'm here.

I have this line in my DTD

Code:
<!ATTLIST module ID label CDATA "ID" #REQUIRED>

Yet the xml validates, even when the ID tag has been removed.
