XForms : Tree edition

[Alexandre FLAMENT]

Hi,

I would to edit a tree structure with XForms. Is it possible ?

My portion of DTD with the tree :

<!ELEMENT STRUCTURE (SELECTION|SEQUENCE)>
<!ENTITY % choice "(SELECTION|SEQUENCE|TASK)*">
<!ELEMENT SELECTION (%choice>
<!ELEMENT SEQUENCE (%choice>

STRUCTURE is the root, SELECTION and SEQUENCE are node, and TASK are leaf.
