3.3.4 The bind Element

Element bind selects a node-set from the instance data with a model binding expression in the nodeset attribute. Other attributes on element bind encode model item properties to be applied to each node in the node-set. When bind has an attribute of type xsd:ID, the bind then associates that identifier with the selected node-set.

Common Attributes: Common, Model Item Properties (Optional)

Special Attributes:

nodeset

An optional attribute containing a model binding expression that selects the set of nodes on which this bind operates.

context

Optional attribute containing an XPath expression evaluated using the in-scope evaluation context. The result of the XPath expression is used to override the in-scope evaluation context. By adjusting the in-scope evaluation context, this attribute affects the evaluation of subsequent attributes that may appear on bind, including nodeset and Model Item Properties.

Editorial note: NickVdB	2008-02-01
If the context attribute is used on insert and delete, only the first node of the nodeset returned by the XPath expression is used as the new in-scope evaluation context. But I think we don't want to limit the new in-scope evaluation context by specifying context on a bind to be limited to the first node.

See 6 Model Item Properties for details on model item properties.

See 7.2 Evaluation Context for details on how the evaluation context is determined for each attribute of the bind element.

<bind nodeset="c" caclulate="../a + ../b" />

<bind nodeset="c">
    <bind context=".." caclulate="a + b" />
</bind>
