RE: [xml-dev] Element Occurrence and #PCDATA

["Dan Mabbutt" <Seigfried@msn.com>]

Betty,

Thanks for the response, but it wasn't quite what I was asking. I'm aware of
the differences between CDATA and #PCDATA. (I only mentioned that because it
was the subject of the single authoritative reference I could find in
Simon's book.) I should have been more clear in my question, but I didn't
want to suggest my own conclusion too strongly.

My question is about the use of the Element Occurrence Indicator in this
syntax.  That would suggest that the DTD is requiring zero or more
occurrences of #PCDATA and I can't quite imagine why it would ever be
meaningful to include that syntax in the DTD.

Dan:

	#PCDATA represents "Parsed Character Data".  Years ago when I
first started working with SGML, I had the same question. I saw the
#PCDATA and thought what is the difference between Personal Computer (PC)
Data and UNIX or VMS data.  Basically is means that the parsers looks at
every character.

	Character Data (CDATA - only valid in attributes and
Marked Sections in XML) says that the parser will not look at the
characters in a CDATA element.

	Hope this helps.

Betty
