OurBigBook
The toplevel header of a OurBigBook file is its first header and the one with the lowest level, e.g. in a document with recommended syntax:
= Animal

== Dog

=== Bull Terrier

== Cat
the header = Animal is the tolevel header.
Being the toplevel header gives a header some special handling described in child sections of the section and elsewhere throughout this documentation.
The toplevel header is only defined if the document has only a single header of the highest level. e.g. like the following has only a single h2:
== My 2

=== My 3 1

=== My 3 2
