Bug#958905: Multiple versions of libocct cannot be installed

[Yuri D'Elia]

Package: opencascade
Version: 7.3.3+dfsg1-2
Severity: minor

My understanding is that when choosing to include the version in the
package name of a library, is that so that we can allow for multiple
versions of the library to coexist on the same system.

However all libocct-* 7.4 libs break 7.3, which defeats the point
of major-minor version in the package name itself.

Would it be possible to avoid the Breaks or there's some underlying
issue?
