Hmm okay makes sense. It is disappointing that the analyst failed to note why he was not happy with the work experience documentation. You mention that all duties were listed so the only possible options areYes. She is two years younger than me so more points!
1. Was her compensation mentioned on the letter or substantiated with any other documentation?
2. Was the letter on official letter head?
3. Were the dates clearly stated for period of employment?
4. Was the date the letter was issued clearly stated?
5. Were the duties listed a good match for the NOC that was chosen?
If answer to all above is yes, then you have nothing to worry about ... but analyst action has caused unjustifiable delay.
