That's not what I see. Instead, I see newlines being turned into 
"<backslash> n" when they're put into the environment variable, 
confirmed from the PoV of the exec'd program:

NAS_PORT_TYPE=Ethernet
REPLY_MESSAGE="foo\nbar"

...the escaping being done by fr_print_string, called from 
vp_prints_value via vp_data_prints_value.

Are you sure you're not doing something like:

Attr += "<xml>
Attr += "<tag/>"
Attr += "</xml>"

...and then getting caught out by only the last attribute ending up in 
the environment?
