You are right that WebIt! does not support this style of SXML.

There are two respects in which WebIt! does not handle
the following SXML fragment:
(*TOP*
  (@ (*NAMESPACES* (c "http://www.cars.com/xml")))
  (*PI* xml "version=\"1.0\"")
  (part (c:item "wheel")))

First, WebIt! is not expecting / does-not-support namespace
declarations at the "document level", only within an element.

Second, WebIt! does not support the element tag in the style
of "c:item". write-xml, for example, will attempt to lookup "c"
as a URI, not as a prefix--and will fail.
