Seeing a software on the Abie's website at www.w3cn.org, it is really convenient.
In the process of making the WEB standard website, we always have to keep the W3C website to verify that the page produced is in line with XHTML 1.0, which is more troublesome. A Real Validator is a local calibration software that allows you to directly verify the page directly without the need to check the verification, and the results of the verification are completely consistent with W3C.
