<!DOCTYPE moviereview.1 SYSTEM "moviereview.dtd" [
<!—

This is the full DTD for movie reviews for the fictitious CyberCinema
movie review site.

Version 1.0

*** 22 August 2001
If all your changes are commented here, it will make the DTD
easier to understand when reading it for the first time.
*** 21 August 2001
A good idea is to have a version log at the top of your DTD in a
comment block like this one.

*** 20 August 2001
Tomorrow I will write another comment above.

<!—
Pull in the regular entity definition for HTML, which includes
things like the British pound sign

<!ENTITY % HTMLlat1 PUBLIC
   "-//W3C//ENTITIES Latin 1 for XHTML//EN"
   "xhtml-lat1.ent">
%HTMLlat1;

<!ENTITY % HTMLsymbol PUBLIC
