ddoc $(BR)

[Unknown W. Brackets]

In that case, check where they are being used.

You can't put <br> elements inside some sorts of elements, such as <ul>. 
  Many people do this, however, because browsers will do it (even though 
it is invalid.)

Sorry for making the assumption that the issue was about XHTML.  Can you 
post the error message you're getting from the validator?

Thanks,
