I cannot get the english pdfs from the site:
<https://www.itu.int/rec/T-REC/en>

I tryed it with the Action: "Get separated files" at following URL:
<https://www.itu.int/rec/T-REC/en>

Scanrules were:
-*
+*.html
+t-rec*PDF-E*



Example of the needed file is: "T-REC-E.164-200405-I!Sup3!PDF-E.pdf"
All documents start with "T-REC-" and have "PDF-E" somewhere in it, so made
the filter: "+T-REC*PDF-E*"
