First a question:
Can I have a DTD that mentions elements
If so, then I can easily nest elements from one dtd inside another.
In the example below, the N1:BOOK element will contain N1:NAME elements,
and elements from a different namespace N2:ADDRESS
If DTD1, which is denoted by URI "uri:dtd1" says
<!ELEMENT N1:BOOK (N1:NAME N2:ADDRESS) >
<!ELEMENT N1:NAME >
and DTD2 says (notice that the prefix K doesn't matter, only the definition
<!ELEMENT K:ADDRESS >
then an valid instance document could be
which would conform to DTD1.
What's wrong with this picture?.....
For my needs, DTD1 is a perfectly fine DTD. It defines
local stuff (NAME,BOOK), and references other DTD's to define the sub pieces.
