allowBlank not documented in possible annotation parameter for QueryParam / RequesParam

[allan-simon]

it seems to be something that has been added recently

I'm currently finishing an other PR , so if someone feel like adding it in the doc

[allan-simon]

and actually it does not work as i would have naively expected
i.e if you put it alone , it let empty string as 'valid' , one has to put together with requirements=".+" to have the expected behaviour of "whatever as long as its not an empty string"

it was added here https://github.com/FriendsOfSymfony/FOSRestBundle/pull/886/files

@allan-simon sadly the regex validator does not work as expected. The RegexValidator ignores everything that is null or an empty string. What documentation can i add to complete this?

[allan-simon]

@mosch , indeed I've seen this ticket on symfony symfony/symfony#10221 I haven't read the full thread but it seems the behaviour is "on purpose and symfony people are well aware of it" and dont plan to fix it , and seems some stuff will change in a far future with symfony/symfony#12312

I guess you can in documentation that allowBlank is the way to go as requirements has this edge base (i'm not a very fluent english speaker, so I can't help on how to phrase it nicely :/ )
