Conformance / sub documents / T&Ds (ODF 1.2 CD01)

Dear all,

1.4.2.1 (D1.1.2) states (of a package):

"it shall contain at least one of the following sub documents: content.xml and styles.xml."

What is a "sub document"? This is the first time the term is used. Is it an entry in the package/archive? If so, these things are referred to later in the specification as "files".

These things should be referred to consistently.

In general, I miss a "terms and definitions" section in ODF. Such a section could, I think, greatly improve the quality of the document.
