+ * PlantUML parses text using regular expressions. To aid in readability, these
+ * are sepecified as trees of {@link RegexComposed} fragments.
+ * 
+ * <p>
+ * Before a {@link RegexComposed} can be matched, it must first have each
+ * of its constituent parts concatenated into one large regex string using
+ * {@link RegexComposed#getFullSlow}. This string is then transformed by
+ * {@link MyPattern.transform} to replace some macros (e.g. %s
+ * for whitespace, %q for single quote) and compiled using
+ * {@link java.util.regex.Pattern#compile}.
