So I am working on this XML project to create a small list of favorite DVDs, etc. Maybe I missed it (or that I may have not gotten this far in my reading) but in my DTD I want to restrict movie_review to only allow (G | PG | PG-13 | R | NC-17)... but for some reason it's not working... here's what I have so far... that has been validated.

<?xml version="1.0" encoding="utf-8"?>

<-- more after this -->

I try varions like this:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE DVDLibrary[
  <!ELEMENT DVDLibrary (DVD)*>
  
  <!ELEMENT DVD (title, genre, movie_rating, viewer_rating, summary, year, director, runtime, studio, cast)>
  <!ATTLIST DVD id ID #REQUIRED>

  <!ELEMENT title (#PCDATA)>

  <!ELEMENT genre (#PCDATA)>

  <!ELEMENT movie_rating (#PCDATA)>
  <!ATTLIST movie_rating movie_rating (G | PG | PG-13 | R | NC-17) >

  <!ELEMENT viewer_rating (#PCDATA)>

  <!ELEMENT summary (#PCDATA)>
  <!ELEMENT year (#PCDATA)>
  <!ELEMENT director (#PCDATA)>
  <!ELEMENT runtime (#PCDATA)>
  <!ELEMENT studio (#PCDATA)>

  <!ELEMENT cast (actor)*>
  <!ELEMENT actor (firstName, lastName)*>
  <!ATTLIST actor idnum ID #REQUIRED>
  <!ELEMENT firstName (#PCDATA)>
  <!ELEMENT lastName (#PCDATA)>
]>

and getting this error...

Open quote is expected for attribute "rating" associated with an element type "movie_rating".

Am I even in the ballpark on this one?
