1. A method implemented at least in part by a computer comprising: determining a correlation between a first node of a first electronic form and a node of a plurality of nodes of a second electronic form based on an annotation to the first node of the first electronic form, the annotation indicating that a first schema fragment governing the first node and a second schema fragment governing the node of the plurality of nodes of the second electronic form indicate that the first node and the node of the plurality of nodes are capable of association; and importing, based on this correlation between the first node of the first electronic form and the node of the plurality of nodes of the second electronic form, data between the first node of the first electronic form and the node of the plurality of nodes of the second electronic form.
