Retrieving the attachment to a SelectPage response
The response to a SelectPage request includes the SelectPageResponse element, a ConnectionHandle to keep the connection open, a MIME boundary and header, followed by the binary attachment.
In SelectPageResponse, PageRef specifies the following properties of the response:

ContentId specifies that the pages return as an attachment.

ContentType is text/html when the requested format is DHTML.

ContentEncoding is binary, meaning that the pages return as binary data.

Locale indicates the locale in which the user can view the selected pages.
