I think this is right.  I used to be a librarian, and one of my favorite 
reference sources is Gale's _Acronyms, Initialisms & Abbreviations 
Dictionary_, which uses 'acronym' in pretty much the same way as Rick. 
Entities like 'XML' and 'XSLT' are described there as *initialisms* 
(perhaps of a degenerate class, since the 'X' is not an initial letter 
of one of the abbreviated words), since they comprise the initial 
letters of the words of in the name they denote.  'SOAP', when 
pronounced like the substance we use when bathing, is an acronym in the 
classical sense, since one is pronouncing not the individual letters but 
a word those letters constitute.  'OPEC' is thus also an acronym.  'SQL' 
can be either, since some pronounce it 'EssCueEl' and others 'sequel'. 
(I always use the former myself.)
