Limitations
Up to 19 different ranks can be used.

Red links
There should be no red links.

This because Taxonavigation is not a taxobox, but a help to navigate between existing hierarchical categories.

Authority
If you provide the authority parameter: parentheses, when present, have a special meaning and must be preserved.

Which classification
Classification is always changing, for that reason there are many different classifications (see for the different classifications of the same family).

So we should always provide the name of the classification with the parameter classification (for example |classification=Cronquist)

Multiple classifications can be provided on the same page with multiple call to.

If there is a conflict between Category:Angiosperms classifications, prefer APG II, which is the future

Available value for classification:
 * Cronquist for for Angiosperms
 * APG II for for Category:Angiosperms
 * APWebsite for (where the future APG III is in preparation) for Category:Angiosperms
 * Sibley for for Birds
 * Smith for for Ferns
