where the last document is understood to be the product of arbitrary, not
predetermined combination - for example where it is not predetermined which
<one> element comes befoe the other <one> element, i have not yet understood
the control information of the kind which i have seen for xml-map to be
sufficient to relabel it.

this would require distinct names. [doesn't matter. it's not a material issue,
'cause i'm not concerned about where the control information is.]

inscrutable, and even ignored, is not the same as none. given that xml
structure has but two dimensions, dominance and sequence, absent predetermined
sequencing constraints, one is left with dominance only. which is not always
sufficient. one has to put up with inscrutable.
