Is interval of proportions a legal data type? If so, which is the correct syntax?

ELEMENT[at0004] occurrences matches {0..1} matches { – Proportion of normal daily intake

value matches {

DV_PROPORTION matches {*}

DV_INTERVAL<DV_PROPORTION> matches {

upper matches {

DV_PROPORTION matches {*}

}

lower matches {

DV_PROPORTION matches {*}

}

}

}

}

… or …

ELEMENT[at0004] occurrences matches {0..1} matches { – Proportion of normal daily intake

value matches {

DV_PROPORTION matches {*}

DV_INTERVAL<DV_PROPORTION> matches {

upper matches {*}

lower matches {*}

}

}

}

… or none of the above?

I would go with something like this

ELEMENT[at0000] occurrences matches {1..1} matches { -- testtest
        value existence matches {0..1} matches {
            DV_INTERVAL occurrences matches {0..1} matches { -- DV_INTERVAL
                lower existence matches {0..1} matches {
                    DV_PROPORTION occurrences matches {0..1} matches
{*} -- DV_PROPORTION
                }
                upper existence matches {0..1} matches {
                    DV_PROPORTION occurrences matches {0..1} matches
{*} -- DV_PROPORTION
                }
            }
        }
    }
