For <ldp-router> to be compliant with Twitter bootstrap navbar, two solutions :

• add <a href="#" class="nav-link">ROUTE NAME</a> as the HTML content of <ldp-route>
• let the user chose the content of <ldp-route>

The active <ldp-route> would also need to receive the active class on top of the active HTML attribute.

That would help me a great deal as a developer to be Bootstrap compliant.

One additional benefit to include a <a> tag is that is automatically mimicks the mouse behaviour on hover and click, which is the bare minimum for a menu I believe.
