Place or attach permanent file to the node edit form I want to make an attachment available for download to the user who is filling out a node edit form. This attachment will be a file template that they will fill out, save, then upload to the filefield field at some point, so I want the attachment to ALWAYS be available on the node edit form. 

I realize I could do this by placing a block on the page via the block admin ui, but I would like to accomplish this using hook_form_alter, because the file that is attach will be specific to certain field within that form having certain values when a user is editing the form. I've provided a visual mock-up for further clarification.
If it's a PDF, you might also want to look into Fill PDF.
