в доке-же всё написано:

Link to Language
Once you finish to defined your parser, you can associate it with Notepad++ internal language id (or with file extension), in order to make it works with the language you want. All you need to do is add association node(s) into associationMap node.

functionList.xml

<!--
if langID cannot be found above, you can still set the file extensions
<association ext="my_passer_ext1" id="my_passer_id"/>
<association ext="my_passer_ext2" id="my_passer_id"/>
-->

т.е. в дополнение к ранее написанному:

<association ext=".p" id="parser3_function" />
