Construct octet values for attributes

How I can construct octet value for VSA if some octet in it has to be `0x00`? For example I can set value for VSA using expression like this ``` VSA-Name := '\001somevalue' ``` or ``` VSA-Name := 0x01736f6d6576616c7565 ``` But when I tried to use this expression ``` VSA-Name := '\001\000somevalue' ``` All data after \000 are truncated -- Vladimir
