BCPFR1 - Cross-Referencing Modules

Module owners MAY cross-references other modules to build either Resource or Pattern modules.

However, they MUST be referenced only by a public registry reference to a pinned version e.g. br/public:avm/[res|ptn|utl]/<publishedModuleName>:>version<. They MUST NOT use local parent path references to a module e.g. ../../xxx/yyy.bicep.

Although, child modules, that are children of the primary resources being deployed by the AVM Resource Module, MAY be specified via local child path e.g. child/resource.bicep.

Modules MUST NOT contain references to non-AVM modules.
