function rich_snippet_normalize_schema in Rich Snippets 7

Normalizes the schema to a value suitable for use in function names.

Converts all characters to lowercase, replaces spaces with underscores. For example, "Health and medical types" -> "health_and_medical_types".

Note that strtolower() is used in favor of drupal_strtolower() since none of the schemata have UTF-8 specific characters.

Return value

string The normalized schema.
