Description of problem

URL to affected spec or repo:

https://w3c.github.io/wot-thing-description/ontology/td

What happened (e.g., it crashed)?: ReSpec always inserts the id title for the document title. However, if there is already a section id with value title in the document, it causes issues with linking to that section.

Expected behavior (e.g., it shouldn't crash): In such cases, respec should display a warning. It can also try to iterate and add title2 etc. Even better would be a configuration option to set a custom title id.

Optional, steps to reproduce:

1. Go to https://w3c.github.io/wot-thing-description/ontology/td#title
2. Expect to land at section 4.3.12 but the window moves to the top of the page, i.e. to the document title

Note: I am not sure why the title needs an id. Maybe removing that addition of the id can make sense?
