Right.  Repetition of individual members of the sequence may be allowed 
according to their individual min/maxoccurs.

</fontfamily>OK. I get that the sequence tag is implicitly there, but
my question was also, the sequence tag's minOccurs and maxOccurs
attributes affect the entire sequence, right? (e.g., the entire
sequence can appear exactly once in this case)  (Another possiblity
might be that the sequence tag's minOccurs and maxOccurs attributes are
defaults for the elements in the sequence.)

</fontfamily>It's 2.7 of the Primer
(http://www.w3.org/TR/xmlschema-0/#groups). Should it be "Each element
in the group may appear once or not at all," or "All the elements in
the group may appear once or not at all". I imagine it is the former.
