044:         * Class contains information about single HTML tag.<br/>
045:         * It also contains rules to for tag balancing. For each tag, list of dependant
046:         * tags may be defined. In order to more easely describe those rules, several
047:         * prefixed are introduced.
048:         * </p>
049:         * <p>
050:         * For each tag, list of dependant tags may be specified using following prefixes:
051:         * <ul>
052:         *      <li>
053:         * 		  <h3>!</h3> fatal tag - required outer tag - the tag will be ignored during
054:         *        parsing (will be skipped) if this fatal tag is missing. For example, most web
055:         *        browsers ignore elements TD, TR, TBODY if they are not in the context of TABLE tag.
056:         *      </li>
057:         *      <li>
058:         *        <h3>+</h3> required enclosing tag - if there is no such, it is implicitely
059:         *        created. For example if TD is out of TR - open TR is created before.
060:         *      </li>
061:         *      <li>
062:         *        <h3>-</h3> permitted tag - it is not allowed to occure inside - for example
063:         *        FORM cannot be inside other FORM and it will be ignored during cleanup.
064:         *      </li>
065:         *      <li>
066:         *        <h3>#</h3> allowed children tags - for example TR allowes TD and TH. If there
067:         *        are some dependant allowed tags defined then cleaner ignores other tags, treating
068:         *        them as unallowed, unless they are in some other relationship with this tag.
069:         *      </li>
070:         *      <li>
071:         *        <h3>^</h3> higher level tags - for example for TR higher tags are THEAD, TBODY, TFOOT.
072:         *      </li>
073:         *      <li>
074:         *        <h3>&</h3> tags that must be closed and copied - for example, in
075:         *        <code>&lt;a href="#"&gt;&lt;div&gt;....</code> tag A must be closed before DIV but
076:         *        copied again inside DIV.
077:         *      </li>
078:         * </ul>
079:         * </p>
080:         * 
081:         * <p>
082:         * Tag TR for instance (table row) may define the following dependancies:
083:         *      <code>!table,+tbody,^thead,^tfoot,#td,#th,tr,caption,colgroup</code>
084:         * meaning the following: <br>
085:         *      <li>TR must be in context of TABLE, otherwise it will be ignored,</li>
086:         *      <li>TR may can be directly inside TBODY, TFOOT and THEAD, otherwise TBODY will be
087:         *      implicitely created in front of it.</li>
088:         *      <li>TR can contain TD and TD, all other tags and content will be pushed out of current
089:         *      limiting context, in the case of html tables, in front of enclosing TABLE tag.</li>
090:         *      <li>if previous open tag is one of TR, CAPTION or COLGROUP, it will be implicitely closed.</li>
