I am trying look at mods for reference so that I try out making my own. I was wondering where the Product is "output" in the XML it doesn't seem to be where I expected it to be which was under the RecipeDefs.

For example, the recycle apparel recipe. The product you receive is a certain amount of fabric. Is this based on the Remaining Hitpoints of the item? How do I produce an item effected by the remaining hitpoints in the ingredients.

Same goes for Mending, I see there is a chance for failure which just completely disassembles the apparel that you're trying to mend. Where is that information in the XML files? Or how can I add that to my own mod.
