<user>response<\user>
Or:
<user|response|
This element is used to distinguish user input from computer output in a computer dialog. It is typically used within the <ex> element, where spaces and line breaks between the <user> start tag and the <\user> end tag are significant.
If used within a paragraph, <user> text must not break across lines in your source file.
The <user> end tag is required if the long form is used.
