q) XML Schema and valid XML documents

Discussion in 'XML' started by Generic Usenet Account, Oct 30, 2009.

  1. Wikipedia provides the following definition for valid XML document

    it contains a reference to a Document Type Definition (DTD),
    and that its elements and attributes are declared in that DTD
    and follow the grammatical rules for them that the DTD

    There is no reference to XML Schema in the above defintion. I am
    presuming that this is a dated definition for valid XML document and
    that an XML document that has an XML Schema associated with it is also
    a valid XML document.

    Kindly confirm.

  2. Without additional context, "valid" means "valid according to its
    DTD", and that's how it's defined in the XML spec. In the context of
    XML Schemas, it can of course mean "valid according to a schema". If
    you want to be less ambiguous, use the term "schema valid" or (since
    there are other schema languages) "XML Schema valid".

    I'm normally fairly pro-Wikipedia, but many of the software articles
    are poor, and certainly the XML stuff.

    There's very little need for WP content on technical issues like this,
    as it's well described elsewhere. This also discourages (or fails to
    encourage) the competent WP editors to do anything about the XML
    content. So read those sources, not WP.

    Oh dear. It has deteriorated, hasn't it? It used to be much better than
    that. When I have more time...
