"v0": Use deprecated sheet article semantics
For sheet nodes there are two cases w.r.t. articles:
(1) Sheet nodes are part of the associated sheetCutting node's article if
the sheetCutting node is the only target of the sheet node.
(2) Sheet nodes form a dedicated article if two or more sheetCutting nodes
are the targets of the sheet node.
"v1": Latest version
Sheet nodes always from a dedicated article regardless of the number of
target nodes.
