I don't believe that is the appropriate approach for John's problem.
He needs a convenient way to insert the <replaceable> </replaceable>
tag in the generated XML. This is formatted as italic by BoostBook
and represents the right semantics to boot.
Replaceable text in code is an important idiom that we used often in
"C++ Template Metaprogramming," and has crucial interactions with the
literate programming/testing system we used to test the examples: you
need to replace the <replaceable> text with something concrete in
order to make the tests work. Of course, ReST doesn't have
<replaceable>, so we just used italics and interpreted all italics in
literal blocks as <replaceable>. ReST has a parsed-literal directive
within which markup is significant, so it was pretty easy:
.. parsed-literal::
template <class T>
struct is_void : public *true-or-false-type* {};
QuickBook needs something similar.
