Generally, the "heavy" symbol for such a thing will have footprint and electrical specs, but no value (or perhaps a default value). So, r0805p1.sym is a 1% tolerance resistor in an 0805 SMT package. In the environments I've worked in, the kitters know what a resistor is, what an 0805 package is, and what 1% tolerance means, so when that info shows up in the BOM, it's adequate. Sometimes I'll include in my informal notes a pointer to a manufacturer and distributer, but for "generic" parts that stuff doesn't go into the BOM. A more automated flow would need a post processing step to obtain part numbers and order codes from the part specs, but that generally doesn't belong in the *design*: that mapping is neither one to one nor stable.
