[DFDL-WG] Rules for resolving ambiguity in the in-scope terminating markup

[Steve Hanson]

Tim - can you clarify the last sentence please - is the terminating markup 
that of the preceding peer element, or the enclosing parent?

These rules seem to work: 
a) separators and terminators are collectively called 'terminating 
markup'. 
b) initiators are not 'terminating markup' 
c) when two items of in-scope terminating markup have a common prefix, the 
parser must give precedence to the longest item. 
d) when two items of in-scope terminating markup have exactly the same 
value, the parser must give precedence to the innermost ( most deeply 
nested ) item. 
e) when the separator and terminator on a group have exactly the same 
value, the parser must give precedence to the separator. 

If an initiated component can occur at the same point as an item of 
terminating markup, the initiator takes precedence.
