Your plugin is simply a cObj (content object) that calls an external PHP
script. If it is an USER or USER_INT object can be specified using
TypoScript. The developer chooses one default, but any user can change
it with TypoScript (e.g "plugin.tx_xxx_pi1 = USER"). The call to
addPItoST43 is just a shortcut to writing the TypoScript on your own.

But now the developer, in it's script, might want to link to itself.

If you have said:

    $this->pi_USER_INT_obj = 1;

Any link to yourself won't expect to be cached (no cHash and
no_cache=1). This is the only use of this variable. Its just a bit
misleading in the name.

Documentation for some useful functions for extentions (including
addPItoST43) can be found in the Core API documentation:

http://typo3.org/documentation/document-library/doc_core_api/Functions_typically/

If you install the extdeveval extention, you will have the API docs that
were extracted from the source a year ago, where you also find the
documentation for this. Or read the source! :)
