Does BPEL Support sending Attachment in EMAIL ?

Question

Hi,
We have a scenario where we want to send an attachment of a file in the email for a Field Force Automation application. Is this possible in BPEL Beta 3 to send an email with an attachment ? Because in the notification service wizard there is no facility for attachment.
The attachment could be even a simple .xml or .txt file.
Regds,

The current versions of the BPEL process manager support sending email attachments using the notification service. When attachments are to be sent via email, in the notification wizard, mark the email as a multipart message. Also set the number of attachments to send. When attachments are to be sent, the content body is set to a MultiPart element that contains as many BodyPart elements as the number of attachments. For example, if there are 2 attachments, a BPEL copy to created to set the content as follows.
<copy>
<from>
<Content xmlns="http://xmlns.oracle.com/ias/pcbpel/NotificationService">
<MimeType>multipart/mixed</MimeType>
<ContentBody>
<MultiPart>
<BodyPart>
<MimeType/>
<ContentBody/>
<BodyPartName/>
</BodyPart>
<BodyPart>
<MimeType/>
<ContentBody/>
<BodyPartName/>
</BodyPart>
</MultiPart>
</ContentBody>
</Content>
</from>
<to variable="emailPayload"
part="EmailPayload" query="/EmailPayload/ns:Content"/>
</copy>
The content entered from the JDeveloper notification wizard is set for the first BodyPart. The rest of the BodyPart elements has to be set using BPEL copy statements as shown below. Each BodyPart has 3 elements - ContentBody, MimeType and BodyPartName. All the three elements must be set for each attachment.
               <copy>
                    <from expression="string('image/gif')"/>
                    <to variable="emailPayload" part="EmailPayload"
query="/EmailPayload/ns:Content/ns:ContentBody/ns:MultiPart/ns:BodyPart[3]/ns:MimeType"/>
               </copy>
               <copy>
                    <from expression="ora:readFile('bpel_logo.gif')"/>
                    <to variable="emailPayload" part="EmailPayload"
query="/EmailPayload/ns:Content/ns:ContentBody/ns:MultiPart/ns:BodyPart[3]/ns:ContentBody"/>
               </copy>
               <copy>
                    <from expression="string('bpel_logo.gif')"/>
                    <to variable="emailPayload" part="EmailPayload"
query="/EmailPayload/ns:Content/ns:ContentBody/ns:MultiPart/ns:BodyPart[3]/ns:BodyPartName"/>
               </copy>
