-/**
- * @fileoverview This is a simple template engine inspired by JsTemplates
- * optimized for i18n.
- *
- * It currently supports three handlers:
- *
- * * i18n-content which sets the textContent of the element.
- *
- * <span i18n-content="myContent"></span>
- *
- * * i18n-options which generates <option> elements for a <select>.
- *
- * <select i18n-options="myOptionList"></select>
- *
- * * i18n-values is a list of attribute-value or property-value pairs.
- * Properties are prefixed with a '.' and can contain nested properties.
- *
- * <span i18n-values="title:myTitle;.style.fontSize:fontSize"></span>
- *
- * This file is a copy of i18n_template.js, with minor tweaks to support using
- * load_time_data.js. It should replace i18n_template.js eventually.
