            <currency:options></currency:options>
        </currency:symbol>
        <currency:convert from="USD|CAD|JPY|..." price="10.95" to="CAD|JPY|...">
            <currency:from></currency:from>

            <currency:to></currency:to>
        </currency:convert>

TAG REFERENCE
  <currency:format>
    Given a price, usually in decimal form, format returns a formatted price
    using the various options in "Locale::Currency::Format".

        <currency:format>
            <currency:price>10.9</currency:price>
        </currency:format>  # prints &amp;#x0024;10.50

    The "format" tag has three available attributes to control the output:

    code
        This is the 3 letter currency code used to specify the currency in
        use. The "code" attribute can also be specified using a child tag
        instead:

            <currency:format>
                <currency:code>USD</currency:code>
            </currency:format>

        "USD" is used as the default if no currency code is specified. See
        Locale::Currency::Format for all of the available currency codes.

    options
        This is a string containing the formatting options to be used to
        specify the desired output format. The "options" attribute can also
        be specified using a child tag instead:

            <currency:format>
                <currency:options>FMT_STANDARD | FMT_NOZEROS</currency:options>
            </currency:format>

        "FMT_HTML" is used as the default if no options are specified. See
        Locale::Currency::Format for all of the available format options.

    price
        This is the price to be formatted. While it can be passed as an
        attribute, the more common usage will be as a child tag:

            <currency:format>
                <currency:price>19.95</currency:price>
            </currency:format>

        You can also next a "convert" tag inside of "price" to format the
        results of a currency conversion:

            <convert:price>
                <currency:convert from="USD|CAD|JPY|..." price="10.95" to="CAD|JPY|...">
                    <currency:from></currency:from>
                    <currency:price</currency:price>
                    <currency:to></currency:to>
                </currency:convert>
            </convert:price>

  <currency:symbol>
    Returns the monetary symbol for the specified currency code.

        <currency:symbol code="USD"/>   # prints $

    The "symbol" tag has two available attributes to control the output:

    code
        This is the 3 letter currency code used to specify the currency in
        use. The "code" attribute can also be specified using a child tag
        instead:

            <currency:symbol>
                <currency:code>USD</currency:code>
            </currency:symbol>

        "USD" is used as the default if no currency code is specified. See
        Locale::Currency::Format for all of the available currency codes.

    options
        This is a string containing the formatting options to be used to
        specify the desired output format. The "options" attribute can also
        be specified using a child tag instead:

            <currency:symbol code="USD">
                <currency:options>SYM_HTML|SYM_UTF</currency:options>
            </currency:symbol>

        "SYM_HTML" is used as the default if no options are specified. See
        Locale::Currency::Format for all of the available format options.

  <currency:convert>
    Converts a price from one currency to another using
    Finance::Currency::Convert::WebserviceX.

        <currency:convert from="USD|CAD|JPY|..." price="10.95" to="CAD|JPY|...">
            <currency:from></currency:from>
            <currency:price</currency:price>
            <currency:to></currency:to>
        </currency:convert>

    The "convert" tag has three available attributes to control the output:

    from
        This is the 3 letter currency code used to specify the currency in
        use. The "from" attribute can also be specified using a child tag
        instead:

            <currency:convert>
                <currency:from>USD</currency:from>
            </currency:convert>

        "USD" is used as the default if no currency code is specified. See
        Locale::Currency for all of the available currency codes.

    price
        This is the price to be formatted. While it can be passed as an
        attribute, the more common usage will be as a child tag:

            <currency:convert>
                <currency:price>19.95</currency:price>
            </currency:convert>

    to  This is the 3 letter currency code used to specify the currency in
        use. The "to" attribute can also be specified using a child tag
        instead:

            <currency:convert>
                <currency:to>USD</currency:to>
            </currency:convert>

        See Locale::Currency for all of the available currency codes.
