My Notes
--------
July 18, 2017

Building block Ψ1 (select node "1" in the larger rectangle, and do Edit > Paste Replacement):
<Rectangle roleName="Ψ1">
  <Rectangle roleName="1"/>
</Rectangle>
But, I want rectangle Ψ1 to be flattened during the operation.
 - making it a forest makes the whole operation fail silently

It should be:
<_-.Rectangle roleName="Ψ1">
  <Rectangle roleName="1"/>
</_-.Rectangle>
This works:
<Rectangle roleName="1"/>

version 2
---------
The only way I can currently do this in Xholon, is with xi:include, which is the Xholon way of doing file inclusion.
The included file has to be a FOREST, when there are more than one top-level nodes.
But psi1.xml could be just (but best to make it part of a FOREST)):
<Rectangle roleName="1"/>

version 1
---------
Using my fixed version of pasteReplacement() in CutCopyPaste.java (Edit > Paste Replacement (from clipboard)):
paste into original rectangle 1:
<_-.Rectangle roleName="Ψ1" operation="replace">
  <Rectangle roleName="101"/>
</_-.Rectangle>

paste into original rectangle 2:
<_-.Rectangle roleName="Ψ2" operation="replace">
  <Rectangle roleName="201"/>
  <Rectangle roleName="202"/>
</_-.Rectangle>

paste into original rectangle 3:
<_-.Rectangle roleName="Ψ3" operation="replace">
  <Rectangle roleName="301"/>
  <Rectangle roleName="302"/>
</_-.Rectangle>

paste into original rectangle 4:
<_-.Rectangle roleName="Ψ4" operation="replace">
  <Rectangle roleName="401"/>
  <Rectangle roleName="402"/>
</_-.Rectangle>

    Figure 2. Architecture of rectangle arrangements. Equivalent to an early
    example of an operad from mathematics called the little 2-cubes operad
    E2. In the terminology of this paper, the only building blocks in E2 are
    rectangles. A building instruction in E2 is an arrangement of nonoverlapping
    rectangles within a larger rectangle. In the composition, the placements and
    aspect ratios of building blocks are retained, but sizes can change. The
    operad E2 is the mathematical description of rectangle configurations as
    they are nested into hierarchies of arbitrary depth. The operad underlying
    Matriarch is far more complex than E2, with more diverse building blocks
    and building instructions.
