Installed packages have versions, but I don't understand why the PURL spec should be limited to talking about only specific versions of installed packages, especially if vers is going to be a related standard. How would you use vers if you can't name the package?

"note": "The version is a package version as expected by apk. The format is typically 'pkgver-rX', where 'pkgver' may include suffixes like '_alpha', '_p1', etc. The '-rX' release suffix is a strong convention but not strictly required for a version string to be valid.",

This doesn't make sense. I don't know if the problem is just that it's not defined properly. The distribution goes in the namespace. What does it mean if a PURL has a distribution in the namespace and in the qualifier? If it makes sense for there two be two distributions, what if there are more than two?
