After you use a template to make a copy into a mpd it is still considered a part even though it uses the ldr extension. It is just listed in session panel list etc because it's editable not much unlike models are.
The "0 Unofficial part" line should tell a parser its a part no matter the extension or location. The line is commonly used in many files in the wild so it has become standard practice to do so. Even more so then using "0 !LDRAW_ORG Unofficial_Part" as that implies it is due to become part of the official library at some point.
