Thanks, these both work, the latter a little better as it accepts -M to get 
case-insensitivity.

for _multi_parts I'd need to add all possible permutations I gather? Anyway, 
this Works For Me (TM):

    local -a attrs
    local parts
    attrs=($(slptool findattrs $words[2] | \
               perl -pi -e 's#\(([^()]+)=[^()]*\),?#$1\n#g'))
    parts="_sep_parts -M 'm:{a-zA-Z}={A-Za-z}'"
    repeat $[${#attrs}*5] do
        parts="$parts attrs ,";
    done
    eval $parts

*5 is an arbitrary value that allows for listing attributes multiple times. 
Not that useful but allowed and it look like the list can be continued almost 
indefinately :-)
I only wonder why it seems to ignore -M ...

Thanks alot,
