If the Git repository is on a Windows shared network drive, for example \healthconnectshare\healthconnect$\Repo\POC,
Import All options will fail to import any items settings file for a decomposed production.

The root cause is in ParseExternalName(), which will return a null internal name for the item's PTD file. Trying to parse the deploy document using EnsLib.EDI.XML.Document will fail with an error like:
unable to open primary document entity 'e:\hs-databases\poc///healthconnectshare/healthconnect$/Repo/POC/ptd/RPCCC_Production_Foo/Stgs-Bar7BC2.xml' at line 0 offset 0

This EnsLib XML document parser doesn't like the double slashes leading the file path, and treats it as a path relative to the default database directory rather than the absolute path.

A workaround is to move the Git repo from a network drive to a local drive, but we need to fix because putting the Git repo on a shared drive is a good idea for mirrored environments.
