Info element & title

I've noticed that the title element, when present in an info element does not always appear. For example:

<chapter>
	<info>
		<title>My Title</title>
	</info>
</chapter>

Is fine, but the same scenario with a procedure instead of a chapter will not display the title in FO output. Moving the title to be a direct child of the procedure will display the title in the output as expected.

I'm more or less curious if this behavior is intentional in docbook's design, and how, for elements where d:info/d:title is not displayed, is the appropriate way to display it in output.
