I believe that Pm mentioned in one of his early posts that the colon in 
Attach:filename.ext would make Attach available as a PageTextVariable. 
So, I would try {$:Attach}, generally, and {=$:Attach} in a pagelist 
iteration, and wrap it with whatever else you need in your template:

[[Attach:{=$:Attach}]]  or
[[Attach:Cookbook/{=$:Attach}]]  or
[[Attach:{=$Group}/{=$:Attach}]]  or
[[Attach:{=$Group}/{$=Name}/{=$:Attach}]]

Note: If your recipe page contains more than one instance of the same 
PageTextVariable, in this case "Attach:", I believe that only the last 
one gets picked up (that is, the one that appears furthest down on the 
page).

Question: Is there a way to iterate over a page to pickup all instances 
of a given PageTextVariable, in this case, Attach:   If not, is there a 
real need for that?
