patch           ::= delete | update | insert
delete          ::= "DELETE" turtleTriples | "AT" path "DELETE" pointedGraph?.
path            ::= turtleSubject (followPredicate | "[" restriction "]" )+
followPredicate ::= "/" turtlePredicate
restriction     ::= path "MATCH" pointedGraph
update          ::= "AT" path "UPDATE" pointedGraph .
pointedGraph    ::= turtleObject | turtleTriples
insert          ::= "INSERT" turtleTriples | path INSERT pointedGraph .


ldp:$ is used denote the current captured node in a path. It can be
used to restrict a path, or as the pointer for a pointed graph (insert
and update).
