+ * <li>mixing of '<code>-</code>' (dash) and '<code>.</code>' (dot)
+ * separators,</li>
+ * <li>transition between characters and digits also constitutes a separator:
+ * <code>1.0alpha1 =&gt; [1, 0, alpha, 1]</code></li>
+ * <li>unlimited number of version components,</li>
+ * <li>version components in the text can be digits or strings,</li>
+ * <li>strings are checked for well-known qualifiers and the qualifier ordering
+ * is used for version ordering. Well-known qualifiers (case insensitive) are:
+ * <ul>
+ * <li><code>alpha</code> or <code>a</code></li>
+ * <li><code>beta</code> or <code>b</code></li>
+ * <li><code>milestone</code> or <code>m</code></li>
+ * <li><code>rc</code> or <code>cr</code></li>
+ * <li><code>snapshot</code></li>
+ * <li><code>(the empty string)</code> or <code>ga</code> or
+ * <code>final</code></li>
+ * <li><code>sp</code></li>
+ * </ul>
+ * Unknown qualifiers are considered after known qualifiers, with lexical order
+ * (always case insensitive),</li>
