[Xy-pic] nested xymatrices

[Ross Moore]

Hi Russell

Try looking at the \xygraph  section of the RM.
You can embed Xy-matrices as sub-parts of the \xygraph
using the !M nodes.

You can even have arrows connecting the matrix cells from
different subparts to each other.

One of the Xymovie examples does this.


Hope this helps,

	Ross Moore
