A mixed content declaration in XML must consist of a starred choice
of #PCDATA and a number of element names (or just be (#PCDATA)). You're
not allowed to put in something like (symposium?,contribgrp?).
In any case, even if it were legal, it would allow exactly the same
content as:
<!ELEMENT metanote
(#PCDATA|emph|meta-received|meta-accepted|meta-revised|
meta-presented|meta-submit|edcode|techeditor|symposium|contribgrp)*>
