Sorry for the late reply. So basically, you've stumbled upon some accidental / undocumented functionality, but I think the use case is interesting. You basically want to explicitly inherit workspace metadata as the project metadata. so those PROJCT_* macros will be the same as the WORKSPACE_* counterparts.

Okay, so two things here:

1. name has validation for basic characters and spaces that stop you from using ${meta:workspaceName}
2. version has validation to only expect a semantic version (ex: 1.1.1)

version is a little more tricky, because it's parsed later on into separate macros: - *_VER_MAJOR, *_VER_MINOR, *_VER_PATCH. I just have to disable the validation upfront, and validate the value that resulted from the variable subsitution after ${meta:workspaceVersion}. I'll have all this fixed in the next version. I'm trying to finish it up this week.
