The drafting rules for standards at the British Standards Institute
specifically say that you should *not* have text like this.
1 Heading 1
Some introductory text
1.1 Heading level 2
Some text
1.2 Another heading 2
Some text
Specifically, the text between 1 and 1.1 should not exist, unless it is an
informative note which makes no difference to the overall content and
meaning of the document.
They call this "hanging text". The reason they disapprove of it is that, if
you make a reference to clause 1 from elsewhere in the document, it is
unclear whether you are referring just to that text, or to clause 1 and all
its subclauses.
Where there is no hanging text, it is entirely clear that a reference to
clause 1 *must* include the subclauses, since there isn't anything else
there.

If you eliminate hanging text, it then becomes clear that it is pointless to
have only one subclause below a clause, you might as well eliminate the
unnecessary heading.
Sometimes, the content of hanging text is important, in which case, make it
a subclause of its own, and make the heading title "General" or
"Introduction" or something like that.
I could wish that some other standards organisations followed drafting rules
as carefull, it would eliminate a lot of errors and ambiguities in their
documents! :-(
