the age of documentation ,i.e.its date of issue,should be relevant as regards legislation/recommendations in force at the date of application.这句话就是觉得后半句的relevant as .....搞不明白。谢谢啦
文件的期限，也就是它发行的日期，应该是有关的。至于相关法律和介绍信，将在申请当日生效。note:as regards 是个词组，是至于的意思：As regards the car, I didn't forget to put an advertisement in the paper.至于那辆车,我没有忘记要在报上登则广告。
