Single quote in specific string text in phpdoc is not parsed correctly

[mvorisek]

Bug report

Please see the demo, the phpdoc should allow " (double quote char) and ' (single quote char) values.

I tried '''' phpdoc type (escape using two double quotes), but it does not work either.

I belive this is a bug. The phpdoc type should parse single quoted string using standard php single quoted string grammar.
