DOCBOOK: A question about DTDDECL warning/errors

[Tourre Johnson <tourre@kinetx.com>]

Hi, I'm totally new to the world of DocBook, DTDs, XML and the like.
I'm attempting to use Jade and after I get the DTDDECL warning I get a
list of errors behind it

see here

C:\>cd jade

C:\JADE>jade -t rtf test.sgm
jade:catalog:26:0:W: DTDDECL catalog entries are not supported
jade:docbook.dtd:62:0:E: cannot open "dbnotn.mod" (No such file or
directory)
jade:docbook.dtd:69:0:E: cannot open "dbcent.mod" (No such file or
directory)
jade:docbook.dtd:79:0:E: cannot open "dbpool.mod" (No such file or
directory)
jade:docbook.dtd:92:0:E: cannot open "dbhier.mod" (No such file or
directory)
jade:docbook.dtd:98:0:E: cannot open "dbgenent.mod" (No such file or
directory)
jade:test.sgm:1:71:E: DTD did not contain element declaration for
document type name
jade:test.sgm:2:8:E: element "CHAPTER" undefined
jade:test.sgm:2:15:E: element "TITLE" undefined
jade:test.sgm:3:5:E: element "PARA" undefined
jade:catalog:26:0:W: DTDDECL catalog entries are not supported
jade:E: cannot open "test.dsl" (No such file or directory)
jade:E: specification document does not have the DSSSL architecture as a
base architecture


Is this normal.  I know Jade doesn't support DTDDECL but are these
errors to be expected?
