/** Allows to assign LML parser arguments from within LML templates. Contrary to {@link AssignLmlMacroTag}, this macro
 * evaluates the passed text. This can be used to evaluate and assign preferences or bundle lines. This macro expects at
 * least one attribute: argument name. Other arguments are joined and evaluated by
 * {@link LmlParser#parseString(String, Object)}. For example (macro aliases used):<blockquote>
 *
 * <pre>
 * <:argument arg0 Value/>
 * <:nls arg1 {@literal @}bundle/>
 * <:preference arg2>#preference</:preference>
 * </pre>
 *
 * </blockquote>Assigned values:
 * <ul>
 * <li>{arg0}: {@code "Value"}
 * <li>{arg1}: {@code "Value extracted from .properties file mapped to 'bundle'."}
 * <li>{arg2}: {@code "Value extracted from Preferences object mapped to 'preference'."}
 * </ul>
 * <p>
 * This macro can be also used with named parameters:<blockquote>
 *
 * <pre>
 * <:argument key="arg0" value="Value"/>
 * </pre>
 *
 * </blockquote>
