If you include the schema for docbook, you need to either redefine the
start pattern defined in the schema for docbook or combine its content
with a new one. Since here you want to replace its definition, the only
option left is to redefine it:


include "docbook.rnc" {
  start = document
}
include "mods3.rnc"
document = element document { meta, content }
meta = ModsSchema
content = { "article" | "book" | "chapter" }

BTW, this last pattern means that content is a value equal to "article",
"book" or "chapter". This is illegal to include that after "meta" if
it's an element and, in any case, probably not what you mean. What
about:

content = { article | book | chapter }

???

Hope that helps.
