Subject: [Boost-build] Strange warning when building docuimentation

When building documentation within a quickbook, boostbook, doxygen
chain, I am getting this message:

warning: Unsupported xml/html tag <_> found

from some doxygen documentation I have which reads:

"The easiest way to generate the lambda expression is to use a Boost MPL
placeholder expression of the form 'metafunction<_>'"

In the build the message comes in this sequence (leaving out many extra

Searching for include files...
Searching for example files...
Searching for images...
Searching for dot files...
Searching for files to exclude
Searching for files to process...
Generating XML output...
Generating XML output for class tti::mf_has_member_data
warning: Unsupported xml/html tag <_> found

Anybody have any ideas why the sequence '<_>' in a doxygen detail block
is producing these warnings, and which documentation building tool is
giving the warning ? I thought it might be doxygen but that
'finished...' line in the bjam output makes me think it is something else.
