 /**
  * The MimeMultipart class is an implementation
  * that uses MIME conventions for the multipart data. <p>
  *
  * A MimeMultipart is obtained from a MimeBodyPart whose primary type
  * is "multipart" (by invoking the part's <code>getContent()</code> method)
  * or it can be created by a client as part of creating a new MimeMessage. <p>
  *
  * The default multipart subtype is "mixed".  The other multipart
  * subtypes, such as "alternative", "related", and so on, can be
  * implemented as subclasses of MimeMultipart with additional methods
  * to implement the additional semantics of that type of multipart
  * content. The intent is that service providers, mail JavaBean writers
  * and mail clients will write many such subclasses and their Command
  * Beans, and will install them into the JavaBeans Activation
  * Framework, so that any JavaMail implementation and its clients can
  * transparently find and use these classes. Thus, a MIME multipart
  * handler is treated just like any other type handler, thereby
  * decoupling the process of providing multipart handlers from the
  * JavaMail API. Lacking these additional MimeMultipart subclasses,
  * all subtypes of MIME multipart data appear as MimeMultipart objects. <p>
  *
  * An application can directly construct a MIME multipart object of any
  * subtype by using the <code>MimeMultipart(String subtype)</code>
  * constructor.  For example, to create a "multipart/alternative" object,
  * use <code>new MimeMultipart("alternative")</code>.
