My note of Nov. 9 covers some of the history regarding "all".  Though I 
was specifically responding to a question about deriving extensions, the 
reasons for limiting maxOccurs to 1 are:  an 80/20 cut attempting to keep 
it simple and to meet a basic need for mapping to unordered fields.  Hope 
this helps.
