Setting attributes from semantic action

Setting attributes from semantic action

During parsing I have a few attributes that I need to set in semantic
action only ( as they are derived from data being parsed and I want to
avoid global variables ). If I use more than one variable passed into
qi::phrase_parse I get very long list of compilation errors. I need a help
badly :-)

ascii::space, val1 ) && iter==last;

return 0;
