I installed bnf.vim (highlights BNF grammar files).
Suppose I have a comment in my code:
/* <BNF>
<S> := <A> | h
<A> := a | b | c | .
</BNF> */
Can Vim be somehow programmed to highlight that comment in BNF syntax, despite the filetype of the whole file?

You can use my SyntaxRange plugin for that.
Either explicitly assign the range, e.g.
:10,20SyntaxInclude bnf
or automatically based on the delimiting patterns:
:call SyntaxRange#Include('<BNF>', '</BNF>', 'bnf')
for many file types vim will use the heredoc names as a clue. For example in php files I'm often creating here docs thus:
<?php
$my_html = <<<html
<h1>Solar</h1>
<p>Is <em>good</em></p>
html;
$my_js = <<<javascript
alert('yeah baby');
javascript;
$my_sql = <<<sql
SELECT user
FROM mytable
WHERE energy = 'solar';
sql;
works beautifully, with only problem being that indentation is problematic (the closing marker cannot have preceding spaces)
