Enchanter Mark and decorative carvings (regardless of the name) only change the general description.
That is, you can have:
"short spear"
"flaming short spear"
"vibrating short spear"
The idea is for very general details. The larger details are what you see when you "look" at it.
"this is a spear about 1 meter long designed mostly to do piercing damage by thrusting it into your oppoenents eye..."
The marks/carvings from my perspective aren't designed for things as specific as "A silver spear with Ganelon engraved on the hilt".
I think that's probably why they didn't allow names to be in there.
