Mapping Rule States (activation, execution, suspension, and de-activation)

This section describes the different states of a mapping rule. A mapping rule can either be activated, suspended, executing, or de-activated.

Let E be the element in the input XML document whose start-tag is being read,

let C be the context element; we define the context element to be the most recently read element for which its end-tag is yet to be read, and

let R be a mapping rule in the xfMap document that is considered for matching (see the search-sets section below, which describes when a mapping rule can be considered for matching),

then the following lists the possible states for a mapping rule R:

1. R is activated, if R matches E.
2. R is executing as long as it is activated and E equals C.
3. R is suspended as long as it is activated and E does not equal C.
4. R is de-activated after E’s end-tag is read.

Note: All mapping rules in the xfMap document are initially deactivated.
