How to define dependency to SCL package in normal package

Issue

• I am trying to build a custom package with dependency to a SCL package, perl516-perl-BSD-Resource.
• This custom package is not a SCL package.
• I added the following line for dependency.

Requires:       %scl_require perl516-perl-BSD-Resource

• But, I got the following error.

error: line 13: Dependency tokens must begin with alpha-numeric, '_' or '/': Requires:       %{_scl_prefix}/perl516-perl-BSD-Resource/enable, perl516-perl-BSD-Resource
