Specific example: Let's say I have demonstrated that I have a graph in the sense of https://www.isa-afp.org/theories/category3/#FreeCategory.html :
lemma i_have_a_graph: shows "graph Obj Arr Dom Cod"
sorry
where the symbols Obj, Arr, Dom, and Cod were defined earlier in the file. This gives me access to the lemmas and theorems stated within the graph locale.
How do I use the symbol path defined within the graph locale?
