How to use "zypper info" with a specific version of a package

Question

I want to query the requires of a package using zypper info:

zypper info --requires my_package

This does not work with a specific version like :

zypper info --requires my_package-1.2.0

Capabilities seem not to be supported by the "info" command of zypper but they work fine when using zypper install (e.g. zypper in my_package=1.2.0)

Is there any way to retrieve the required packages of a given package/version by using zypper ?

I could also use rpm, but only when the rpm is accessible in the file system. Maybe some packages are only integrated as zypper services.

Any help is appreciated.
