AUR won't accept PKGBUILD with numbers in the Package Name

Question

Trying to submit a PKGBUILD called:
gstreamer0.10-pitfdll-cvs
I am getting an error "Invalid name: only lowercase letters are allowed."
Does this mean that numbers are not allowed in the package names in AUR?
The error goes away once I remove the numbers but that creates other errors, such as a mismatch with the name in the PKGBUILD file.
This package is just another plugin for the gstreamer0.10 series of packages in Arch.
