quail_api_guidelines.inc in Quail API 8

Contains quail guideline class objects for the quail api.

The guidelines here are modified versions provided by quail. They are intended to be used against indidivual snippets of html and not an entire page.

The quail library will look for guidelines by searching for a function called "${name_ofguideline}Guideline". Therefore, for a class of quail_api_allGuideline, the name of the guideline is 'quail_api_all'. This file must also be included before calling quail(), otherwise this guideline will not be found by the quail library.
