One note.  There's another option here using generated content in CSS:

<span class="money"><span class="transaction-type" title="debit"><abbr  
class="currency" title="USD">$</abbr><span class="amount">777</span></ 

Where we then specify

.transaction-type[title="debit"] abbr:before {
	content: "-";

To get the desired effect in display (in supported browsers).
