17.15.1.79 showEnvelope

This element specifies that an e-mail message header shall be displayed when this document is opened, if an e- mail header is supported by the application opening the file.

If this element is omitted, then applications shall not display the e-mail message header automatically when this file is opened, even if one is available in the application opening the file.

[Example: Consider a WordprocessingML document which should show an e-mail message header when opened. This requirement is specified using the following WordprocessingML in the document settings:

<w:showEnvelope w:val="true" />

The showEnvelope element’s val attribute has a value of true specifying that an e-mail message header must be displayed when the document is viewed, whenever such functionality is available. end example]

This element’s content model is defined by the common boolean property definition in 17.17.4.
