Hmmm, tricky, but I think your context suggests that the texts or documents are to be certified or endorsed in some way. Below is the entry for "viser" from the University of Ottawa's legal glossary. FHS Bridge's Council of Europe legal dico says visa can mean a "memorandum certifying that a formality has been complied with" which seems the kind of meaning you need here.



viser
endorse/to (a warrant) L.R., c. Y-1; 26.4(2)
copie visée
endorsed copy (of an application) C. cr.; 109(7)
délivrer ou viser
issue or endorse/to (a warrant) L.R., c. E-23; 11
différend non visé dans le compromis
dispute not contemplated by the submission to arbitration L.R., c. C-34.6; ann. VII, 34(2)(a)(iii)
dûment visé
duly certified (copy of the Statutes of Canada) L.R., c. S-21; 6
émettre, viser ou accepter
issue, certify or accept/to (a cheque or bill of exchange) L.R., c. B-1.01; 438(1)(b)/ c. T-19.8; 424(1)(b)
mandat visé ou mandat provisoire
endorsed warrant or provisional warrant (to apprehend a fugitive) L.R., c. F- 32; 6(2)
traite ou chèque visés
certified draft or cheque L.R., c. C-3; ann. 2(1)(a)
visé/être

Though visa is used is a legal term, here you need something that works in both verb and noun form. I think you could safely use certification/certify or even endorsement/endorse, though the first seems preferable given the entries above.

Visa suggests a stamp or signature, i.e. something relatively brief. But here the \"visa\" contains quite a bit of information - a reference to the agreement and its preamble, the committee\'s meeting and so on. So while you could say \"visa/provide visas for certain docs\", I think \"certificate/certify\" would be better understood in English. Viser, while it also means aim at, direct at, in the general sense, has the following legal meanings according to Bridge: \"specify, involve, countersign, initial\". None of those really work here. Tricky!
