Hi Doug:

This is for the User's Guide:

Restriction for decorating class graphs with syntax:

In Demeter/Java and AP-Studio, it is beneficial to
think of syntax to be either associated with a node
or an edge in the class graph. For example,

A = "before_node_A" 
    B "after_edge_A_B" 
    C "after_edge_A_C"
    [D "after_edge_A_D"] 
    "after_node_A".

indicates where the syntax is intended to belong. When Demeter/Java 
generates a PrintVisitor, it computes an assignment of syntax to
nodes and edges. AP-Studio does the same when it turns a textual class
dictionary into a graphical representation.

There are class dictionaries where an assignment of syntax to
nodes and edges is impossible:

A = [B] "is" [D].

"is" cannot be attached to an edge nor a node. Therefore, syntax between
optional parts is disallowed. Currently, this rule is "enforced" by
giving a wrong result. A checker will be added.
When you enter the syntaz with AP-Studio you can express the syntax
for each node and edge.

Currently, the class dictionary notation does not allow to express 
the assignment of syntax to nodes and edges. A default assignment is used.
