- * <p>
- * Within a <i>String</i>, <code>"''"</code> represents a single
- * quote. A <i>QuotedString</i> can contain arbitrary characters
- * except single quotes; the surrounding single quotes are removed.
- * An <i>UnquotedString</i> can contain arbitrary characters
- * except single quotes and left curly brackets. Thus, a string that
- * should result in the formatted message "'{0}'" can be written as
- * <code>"'''{'0}''"</code> or <code>"'''{0}'''"</code>.
- * <p>
- * Within a <i>SubformatPattern</i>, different rules apply.
- * A <i>QuotedPattern</i> can contain arbitrary characters
- * except single quotes; but the surrounding single quotes are
- * <strong>not</strong> removed, so they may be interpreted by the
- * subformat. For example, <code>"{1,number,$'#',##}"</code> will
- * produce a number format with the pound-sign quoted, with a result
- * such as: "$#31,45".
- * An <i>UnquotedPattern</i> can contain arbitrary characters
- * except single quotes, but curly braces within it must be balanced.
- * For example, <code>"ab {0} de"</code> and <code>"ab '}' de"</code>
- * are valid subformat patterns, but <code>"ab {0'}' de"</code> and
- * <code>"ab } de"</code> are not.
+ * <p>Within a <i>String</i>, a pair of single quotes can be used to
+ * quote any arbitrary characters except single quotes. For example,
+ * pattern string <code>"'{0}'"</code> represents string
+ * <code>"{0}"</code>, not a <i>FormatElement</i>. A single quote itself
+ * must be represented by doubled single quotes {@code ''} throughout a
+ * <i>String</i>. For example, pattern string <code>"'{''}'"</code> is
+ * interpreted as a sequence of <code>'{</code> (start of quoting and a
+ * left curly brace), <code>''</code> (a single quote), and
+ * <code>}'</code> (a right curly brace and end of quoting),
+ * <em>not</em> <code>'{'</code> and <code>'}'</code> (quoted left and
+ * right curly braces): representing string <code>"{'}"</code>,
+ * <em>not</em> <code>"{}"</code>.
+ *
+ * <p>A <i>SubformatPattern</i> is interpreted by its corresponding
+ * subformat, and subformat-dependent pattern rules apply. For example,
+ * pattern string <code>"{1,number,<u>$'#',##</u>}"</code>
+ * (<i>SubformatPattern</i> with underline) will produce a number format
+ * with the pound-sign quoted, with a result such as: {@code
+ * "$#31,45"}. Refer to each {@code Format} subclass documentation for
+ * details.
+ *
+ * <p>Any unmatched quote is treated as closed at the end of the given
+ * pattern. For example, pattern string {@code "'{0}"} is treated as
+ * pattern {@code "'{0}'"}.
+ *
+ * <p>Any curly braces within an unquoted pattern must be balanced. For
+ * example, <code>"ab {0} de"</code> and <code>"ab '}' de"</code> are
+ * valid patterns, but <code>"ab {0'}' de"</code>, <code>"ab } de"</code>
+ * and <code>"''{''"</code> are not.
+ *
* <p>
* <dl><dt><b>Warning:</b><dd>The rules for using quotes within message
* format patterns unfortunately have shown to be somewhat confusing.
* In particular, it isn't always obvious to localizers whether single
* quotes need to be doubled or not. Make sure to inform localizers about
* the rules, and tell them (for example, by using comments in resource
- * bundle source files) which strings will be processed by MessageFormat.
