Depends on situation and amount of data. I'm using it for tree
structure on <li> element and setting variables like:
"_lft:5 _rgt:10 _parent_id:1 _root". I think this is very simple and
clean solution for this situation. I'm open to any other suggestions.

Nice. I don't know how I thought that \w is for letters only :-)

It's validation limit. As it isn't meant for complex data it's not
that big restriction. You could use '.' instead of '-' and it would be
valid too. I've choose '-' for separator because code looks lot
cleaner to me.

Thank you for review,
