Regression: "Allow annotations ..." started to cause failures for citeproc-py

[yarikoptic]

I believe (through manual bisection) that it was d1bd9b26f024d66d2fc9cbda69a2448af84d86cd (" Allow annotations on top-level body") included in 2.6.2 which introduced a regression which causes citeproc-py failures (https://github.com/brechtm/citeproc-py/issues/94).

edit: this is the rnc file - -https://github.com/citation-style-language/schema/blob/e295d632a7548470457761d63cb9dad561afa84d/csl.rnc

[djc]

Could you provide a minimal reproduction, please?

Let me shine my ignorance in the subject ;)

if before

namespace dc = "http://purl.org/dc/elements/1.1/"

dc:title [ "Citation Style Language" ]

worked before and produced

$> rnc2rng min.rnc
<?xml version="1.0" encoding="UTF-8"?>
<grammar xmlns="http://relaxng.org/ns/structure/1.0"
         xmlns:dc="http://purl.org/dc/elements/1.1/">
  <dc:title>Citation Style Language</dc:title>
</grammar>

now rnc2rng requires start to be present before defining any terms (e.g. dc:title).

In csl.rnc we have start further down within div

I could move it up, but that moves it then also in produced .rng and I am not sure if that does not matter or if desired:

I do not know if that is CSL format requirement to have start high up in the definition?

any further information I could provide to facilitate a fix?
