In your VirtualCollection, implement Sabre\DAV\IQuota:

The 'standard webdav' way is to use {DAV:}current-user-privilege-set. You
can enable this by using Sabre\DAVACL\IACL.
If you enable that, then you also no longer have to do access control
checks on every single method, because the ACL plugin will do that for you
and send back appropriate error codes (403 really).
However, Windows won't do anything with those properties. (Modern) windows
clients use a different property, namely:
{urn:schemas-microsoft-com:}Win32FileAttributes
I don't think they are able to use {DAV:}readonly, but I'm not sure. I'm
also not sure what the format is of this Win32FileAttributes property.
To send back custom properties from a Collection or File object, implement
Sabre\DAV\IProperties.
