Introduction to XHTML Basic/Mobile Profile

The XHTML Basic document type includes the minimal set of modules required to be an XHTML host language document type, and in addition it includes images, forms, basic tables, and object support. It is designed for Web clients that do not support the full set of XHTML features; for example, Web clients such as mobile phones, PDAs, pagers, and settop boxes. The document type is rich enough for content authoring.

XHTML Basic Document Conformance and Validation
A Conforming XHTML Basic document is a document that requires only the facilities described as mandatory in this specification. Such a document must meet all of the following criteria:

  1. The document must conform to the constraints expressed in Appendix B.
  2. The root element of the document must be <html>.
  3. The name of the default namespace on the root element must be the XHTML namespace name,
  4. There must be a DOCTYPE declaration in the document prior to the root element. If present, the public identifier included in the DOCTYPE declaration must reference the DTD found in Appendix B using its Formal Public Identifier. The system identifier may be modified appropriately.

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML Basic 1.0//EN"

  5. The DTD subset must not be used to override any parameter entities in the DTD.
  6. Using W3C MarkUp Validation Service, validate the codes.
