0.5.x Branch and release

[jbielick]

Greetings, @szajbus

We recently encountered a case in which we needed to constrain the element matches to those within a parent element.

We implemented this functionality in this commit and will use our fork to solve the problem in our application. We had to write this feature against 0.5.2 because we're still on 0.5.2—some later releases like 0.6 and 0.7 had breaking API changes that we are unable to upgrade to.

I'm wondering how you feel about the functionality implemented before I try to pull request it against this repo. If you were interested, I would request that we create a 0.5.x branch, implement the feature, tag a 0.5.3 release, and publish it. I could then port the feature to the 0.7.0 tip.

Hi @jbielick,

I think it would be a really good addition to the library and would love to see it implemented. I'm happy to publish it to 0.5.x and 0.7.x lines.

Thanks!
