17-Dec-2019 10:44
This validator checks the markup validity of Web documents in HTML, XHTML, SMIL, Math ML, etc.If you wish to validate specific content such as RSS/Atom feeds or CSS stylesheets, Mobile OK content, or to find broken links, there are other validators and tools available.
In this case, I opted to publish my Sitemap file on the Web.Errors in XML documents will stop your XML applications.The W3C XML specification states that a program should stop processing an XML document if it finds an error.Here is a snippet of the current source of my sitemap showing some of those image:image tags: By default, the validation service you are using seems to be using the sitemap schema at validate the sitemap document.
That schema has a wildcard that will match your elements, but those elements are declared in a separate schema document at not in the schema being used.As the error message says, the wildcard in question is a 'strict' one, meaning the elements it matches must be declared in the schema.
