docs: Convenience method for adding several tags to preserve
  in form of a delimiter-separated String.<p>
  
  The String will be <code>{@link CmsStringUtil#splitAsList(String, char, boolean)}</code>
  with <code>tagList</code> as the first argument, <code>separator</code> as the
  second argument and the third argument set to true (trimming - support).<p>
  
  @param tagList a delimiter-separated String with case-insensitive tag names to preserve by
  <code>{@link #stripHtml(String)}</code>
  @param separator the delimiter that separates tag names in the <code>tagList</code> argument
