Tagged Value value contains #NOTES#

[Michael_Giroux]

Using 6.5 805
I added a tagged value to a class then added some notes to the tagged value.

When I exported the desin to XMI, the application that reads the xmi failed because the value of the tagged value was no longer simply "true" or "false", it was "true#NOTES#bla bla bla"

I am about to modify the application to truncate the value for tagged values at the #NOTES# string, but I wanted to know:
1. are there other elements that use this same technique?
2. If an element value is altered by EA, are there other types of alterations besides #NOTES#?

Is there a document describing this strategy?
