Make the sections of the ODbL linkable

[zygoballus]

You can link to the ODbL with https://opendatacommons.org/licenses/odbl/1-0/index.html, but there is currently no way to link to a specific section of the license. For example, I might want to link to section 4.3 if I'm trying to explain to someone the attribution requirements for Produced Work. This could easily be accomplished by adding HTML id attributes to the paragraph tags for those sections, for example:

<p id="4.3">4.3 Notice for using output (Contents). Creating and Using a Produced
Work does not require the notice in Section 4.2. However, if you
Publicly Use a Produced Work, You must include a notice associated with
the Produced Work reasonably calculated to make any Person that uses,
views, accesses, interacts with, or is otherwise exposed to the Produced
Work aware that Content was obtained from the Database, Derivative
Database, or the Database as part of a Collective Database, and that it
is available under this License.</p>

I could then link directly to the relevant section with https://opendatacommons.org/licenses/odbl/1-0/index.html#4.3.
