I did not think it was true that any Texinfo content started a paragraph.
There were problems with the @image command in the past.  From the manual:

     If an image is the first thing in a paragraph and followed by more
  text, then you should precede the ‘@image’ command with ‘@indent’ or
  ‘@noindent’ to indicate the beginning of paragraph formatting.  This is
  especially important for TeX output to get correct paragraph
  indentation.

If this still true, then it is possible to treat the raw block commands
in a similar way to @image so that they do not start paragraphs?  So the
following would not start a paragraph:

  aaa
  
  @docbook
  <title>etc.</title>
  @end docbook

whereas the following would:

  aaa
  
  @indent
  @docbook
  <title>etc.</title>
  @end docbook

Does that sound ok?
