No, it only operates on section numbers, like all the other API
modules operating on sections. You can still grab a section by its
name by grabbing the section tree from
action=parse&prop=sections&page=Page_name , and extracting the section
number from that tree.

I guess it's simpler to extract a labelled section with a substring search into the whole raw content. ;-) Thanks Roan.
