So far I haven't seen embedded Onix files in epub3 books either. AFAIK, Onix references are mostly used to indicate 13 digit ISBN numbers. For example:
Code:
<dc:source id="src-id">urn:isbn:9780141194523</dc:source>
<meta property="identifier-type" refines="#src-id" scheme="onix:codelist5">15</meta>
<dc:identifier id="book_id">urn:isbn:9780141963624</dc:identifier>
<meta property="identifier-type" refines="#book_id" scheme="onix:codelist5">15</meta>
(
ONIX code list 5 contains product identifier types. 15 = ISBN-13.)
