Subject: Re: Problem with expansion of entities in the internal DTD set
DOCTYPE processing has been broken for as long as i can remember ;)
I'm not quite sure how Hans wants to handle the internal subset, but
for reference: an internal doctype looks like this:
1. <!DOCTYPE
2. a word that is the top-level element, like
article
3. optional: either
PUBLIC
or
SYSTEM
3a. PUBLIC keys are an sgml quoted string (with ' or ") that gives
the external reference, optionally followed by
another quoted string that is a filesystem locator
for the DTD.
3b. SYSTEM keys are an sgml quoted string that is the
filesystem locator for the DTD
4. Next is an optional internal subset.
5. >
So, assuming Simon's example, the following are all legal
(some only in XML I think):
----
<!DOCTYPE article PUBLIC '-//OASIS//DTD DocBook XML V4.1.2//EN'
"file:///var/share/sgml/docbook/dtd/xml/4.1.2/docbookx.dtd"
[
<!ENTITY date "2002-06-XX">
<!ENTITY revno "0.0.2">
]>
----
<!DOCTYPE article PUBLIC '-//OASIS//DTD DocBook XML V4.1.2//EN'
"file:///var/share/sgml/docbook/dtd/xml/4.1.2/docbookx.dtd"
>
----
<!DOCTYPE article PUBLIC '-//OASIS//DTD DocBook XML V4.1.2//EN'
[
<!ENTITY date "2002-06-XX">
<!ENTITY revno "0.0.2">

-----
<!DOCTYPE article PUBLIC '-//OASIS//DTD DocBook XML V4.1.2//EN'
>
----
<!DOCTYPE article SYSTEM
"file:///var/share/sgml/docbook/dtd/xml/4.1.2/docbookx.dtd"

<!DOCTYPE article SYSTEM

----
<!DOCTYPE article
[
<!ENTITY date "2002-06-XX">
<!ENTITY revno "0.0.2">
]>
----
<!DOCTYPE article
