initialism 与acronym的区别?

Wikipedia, the Free Encyclopedia 的解释：
Acronyms and initialisms are abbreviations formed from the initial letter or letters of words, such as NATO and XHTML, and are pronounced in a way that is distinct from the full pronunciation of what the letters stand for.
Of the two words, acronym is the much more frequently used and known, and many speakers and writers refer to all abbreviations formed from initial letters as acronyms. However, some differentiate between acronyms and initialisms: an acronym is a pronounceable word formed from the initial letter or letters of the constituent words, such as NATO (nay-toe), and an initialism is an abbreviation pronounced as the names of the individual letters, and is formed only from the initial letter of constituent words, such as TLA (tee el ay). This distinction is supported by many dictionary definitions, but not by all.
