    - #### canUseSchemaValidation

          public static boolean canUseSchemaValidation()

    - #### escape

          public static java.lang.String escape(java.lang.String text)

      Escapes invalid XML characters in the given character data using XML entities. For the moment, only the following characters are being escaped: (<), (&), (') and ("). Remark: we don't escape the (>) character to keep the readability of the configuration mapping! The XML spec only requires that the (&) and (<) characters are being escaped inside character data.
      Parameters:
        `text` - the character data to escape
      Returns:
        the escaped character data
