 /**
 22  
  * Used on component and transformer methods that have a {@link org.mule.api.annotations.Transformer} annotation.
 23  
  * This annotation marks the method parameter that will be used to pass in one or more of the received attachments.
 24  
  * This annotation can define a single attachment, a comma-separated list of attachment names, or '*' to denote all headers. By default,
 25  
  * if a named header is not present, an exception will be thrown. However, if the header name is defined with the '?' post fix, it
 26  
  * will be marked as optional.
 27  
  * <p/>
 28  
  * When defining multiple attachment names i.e. InboundAttachments("shipping-slip.pdf, customer-record.xml") or using the '*' wildcard to denote all attachments,
 29  
  * or wildcard expressions can be used, such as '*.pdf' or multiple patterns such as '*.pdf, *.xml'.
 30  
  * the parameter can be a {@link java.util.Map} or {@link java.util.List}. If a {@link java.util.Map} is used, the header name and value is passed in.
 31  
  * If {@link java.util.List} is used, just the header value is used. If a single header name is defined, the header type can be used as the parameter or
 32  
  * {@link java.util.List} or {@link java.util.Map} can be used too.  Entry type for collections is {@link javax.activation.DataHandler}.
 33  
  *
 34  
  * The Inbound attachments collection is immutable, so the attachments Map or List passed in will be immutable too. Attempting to write to the Map or List will result in an {@link UnsupportedOperationException}.
