Bug#912684: perl-modules-5.28 needs versioned Provides for modules it bundles

[Adrian Bunk]

Package: perl-modules-5.28
Version: 5.28.0-3
Severity: serious

perl-modules-5.28 has
  Replaces+Breaks: libextutils-parsexs-perl (<< 3.390000)

This makes libextutils-parsexs-perl in unstable not installable.

libextutils-parsexs-perl does have reverse dependencies
in unstable, including revers dependencies with versioned
dependencies.

Versioned Provides for such modules are required.
