The modular schemas are mostly not independently usable.  The module
you're looking at, for <div> and <p>, not surprisingly refers to
element and attribute declarations in many other 'lower level'
modules.  The complete list appears to me to be:

 xhtml-attribs-1.xsd
 xhtml-bdo-1.xsd
 xhtml-csismap-1.xsd
 xhtml-datatypes-1.xsd
 xhtml-edit-1.xsd
 xhtml-form-1.xsd
 xhtml-hypertext-1.xsd
 xhtml-image-1.xsd
 xhtml-inlstyle-1.xsd
 xhtml-link-1.xsd
 xhtml-list-1.xsd
 xhtml-meta-1.xsd
 xhtml-object-1.xsd
 xhtml-pres-1.xsd
 xhtml-ruby-1.xsd
 xhtml-script-1.xsd
 xhtml-style-1.xsd
 xhtml-table-1.xsd
 xhtml-text-1.xsd
 xhtml11-model-1.xsd

However, it is not in general safe to just xs:include all of those --
the xhtml11.xsd top-level driver gets all but xhtml11-model-1.xsd via
xhtml11-modules-1.xsd, which in turn _xs:redefines_ rather than
xs:includes some of the above, namely

 xhtml-csismap-1.xsd
 xhtml-form-1.xsd
 xhtml-hypertext-1.xsd
 xhtml-image-1.xsd
 xhtml-object-1.xsd

So you're really better off just xs:including the top-level driver and
getting everything, i.e. xhtml11.xsd itself.
