The idea is that like the old "View Source" notion, users of a Web map built with MapML should be able to copy-and-paste idiomatic structures so they can be re-used and re-purposed by users, in a user-becomes-developer scenario.

We can facilitate this to some extent, by providing affordances to achieve narrower tasks.

Examples might include copying the current extent via a menu option, as a MapML <meta name="extent" content="...">, or copying a <feature > element.
