   RE: [xml-dev] Question regarding PSVI..

[ Lists Home | Date Index | Thread Index ]

that helps. I think if there are constructs like where you check the
results of path expressions as to whether they are instances of some
types, then we need type assignment.

regarding updates -- I had a question how updates work with wildcards.

I presume the following schema is correct..

<xs:element name="billTo">
      <xs:element name="name" type="xs:string"/>
      <xs:element name="address" type="xs:string"/>
      <xs:element name="zip" type="xs:integer"/>
      <!-- extension. one can put anything here -->
      <xs:any namespace="#all" processContents="skip" />

now, consider the tree (impractical, but still..)


Now consider an update (delete the first zip element) --


Now, I hope both the documents are valid w.r.to the schema?? -- also, will
the type assignment for <zip>90024</zip> change during the update??

cheers and regards - murali.
