* Simple Placeholder-based Localization

* title-msg="message-key" or alt-msg="message-key" attributes. <html:msg /> elements will be replaced
* with localized text, elements with title-msg and alt-msg attributes will receive localized title
* and alt attributes.
* *
* Example:
* <p class="somethingCool">
* <html:msg key="my-message" />
* <img src="something.jpg" title-msg="my-title-message" alt-msg="my-alt-message" />
* </p>
*
* Localizes to...
* <p class="somethingCool">
* My Message
* <img src="something.jpg" title="My Title Message" alt="My Alt Message" />
* </p>
