Description Michael Kay 2007-03-23 15:00:19 UTC

As far as I can see, the data model spec doesn't adequately cover the
determination of the typed value for an element whose schema type is a complex
type with simple content.

Section 3.3.1.2 says: "The process begins with T, the schema type of the node
itself, as represented in the PSVI. For each primitive or ordinary simple type
T, the W3C XML Schema specification defines a function M mapping the lexical
representation of a value onto the value itself."

This doesn't seem to cover the case where T is a complex type with simple
content. In such cases I think T needs to be the {content type} of the schema
type of the node.

I'm inclined to agree with Mike. I think we can fix this by changing the third
paragraph of 3.3.1.2 to read:

The types of the items in the typed value of a node are determined as follows.
The process begins with a type, T. If the schema type of the node itself, as
represented in the PSVI, is a complex type with simple content, then T is the
{content type} of the schema type of the node; otherwise, T is the schema type
of the node itself. For each primitive or ordinary simple type T, the W3C XML
Schema specification defines a function M mapping the lexical representation of
a value onto the value itself.

The WGs decided to accept the text in commend #1 as the resolution of this bug.
