LOL, well there you go :-)

Interestingly, the second document is a 503 type which we do not use very often (internally TE Connectivity in NL), but I want to start using again (because it takes ages for the testlab to make a testreport, and this type allows us engineers to do our own testreport). Just talked to our documentation guy today about this.
