Re: [docbook] Re: [xml-dev] Multiple DOCTYPE in one xml document?

[Wolfgang Laun <wolfgang.laun@gmail.com>]

According to  "Extensible Markup Language (XML) 1.1 (Second Edition)"
http://www.w3.org/TR/2006/REC-xml11-20060816

document ::= ( prolog element Misc* )
prolog ::= XMLDecl Misc* (doctypedecl Misc*)?
doctypedecl ::= '<!DOCTYPE' ...

You can have at most one DOCTYPE, between the XML declaration and the
root element, optionally surrounded by processing instructions and
comments.
