* Message builder for plain text payloads.

* This builder processes the input message as plain text and wraps
* the text in a wrapper element. The name of the wrapper element can
* be configured as a service parameter (see {@link BaseConstants#WRAPPER_PARAM}).
* It defaults to {@link BaseConstants#DEFAULT_TEXT_WRAPPER}.
* If the content is provided as an {@link InputStream} and the content type specifies a
* <tt>charset</tt> parameter (e.g. <tt>text/plain; charset=ISO-8859-15</tt>),
* this information is used to decode the text.
* If the content is provided as an {@link InputStream} but no <tt>charset</tt> parameter
* is specified on the content type, the default charset encoding specified by
* {@link MessageContext#DEFAULT_CHAR_SET_ENCODING} is used.
