Correct VirtualDocumentRoot directive

Question

What should be the correct value for the VirtualDocumentRoot directive if I have the following folder structure:

/example.com/
/example.co.uk/

and wanted to be able to access it using either example.com.localdev or www.example.co.uk.localdev

I have tried the following conf but it fails:

<VirtualHost *:80>
  UseCanonicaName Off
  ServerAlias *.localdev
  VirtualDocumentRoot "E:/workspace/%-2+/html"
</VirtualHost>

and host file has been configured using AcrylicDNS: 127.0.0.1 *.localdev
