Question on wap_push_pap_mime.c- Extension Headers

This module contains the pass_extension_headers() function, the purpose
of which is to valid the structure of extension headers in the Push message.
However, the function contains the line of code -

        if ((octstr_case_search(*body_part, octstr_imm("Content"), 0)) < 0)
            goto end; 

which fails completely if the message body actually contains the word 'Content'.

Why is this check necessary at all - at this point the message could contain a
mixture of WAP header extensions, User header extensions and non-normative
Internet header extensions - so what's the point in looking for a specific keyword ?

Also, on a related note, the pass_data_headers() function looks for headers of
type Content-Transfer-Encoding, Content-ID and Content-Description. These are not
listed among the generic headers in 6.2.1 (WAP-145-PushMessage), so why are they
expected ?
