### ~~`fo:flow-map`~~
* The `fo:flow-map` is used to specify the assignment of flows to regions.
* The `fo:flow-map` formatting object generates no area directly. It is used by the `fo:page-sequence` formatting object to assign flows to regions. Each `fo:flow-assignment` child of the `fo:flow-map` defines a source list and a target list. The source list is a sequence of **flow-names** whose corresponding fo:flow objects (in the referring `fo:page-sequence`) are treated as a single `fo:flow` for composition purposes. The target list is a sequence of **region-names** which identify the region or regions on each page which are used for the source content.
> Note: This is independent of the actual sequence of pages, which is generated as it has always been generated using the `fo:simple-page-master`, and `fo:page-sequence-master` objects referred to by the `master-reference` property of the `fo:page-sequence`.
* For each `fo:flow-assignment` child of the `fo:flow-map`, having an `fo:flow-source-list` child **S** and an `fo:flow-target-list` child **T**, we say that the `fo:flow-map` assigns each of the flows referenced by the `fo:flow-name-specifier` children of **S** to the regions referenced by the `fo:region-name-specifier` children of **T**.
#### ~~`fo:flow-assignment`~~
* The `fo:flow-assignment` is used to specify the assignment of one sequence of flows to a sequence of regions.
* The `fo:flow-assignment` formatting object generates no area directly. It is used by the fo:page-sequence formatting object to assign flows to regions.
* The children of the `fo:flow-assignment` are a source-list and target-list containing constraints for assigning one sequence of flows to a sequence of regions.
##### ~~`fo:flow-source-list`~~
* The fo:flow-source-list is used to specify the sequence of flows to assign in a particular fo:flow-assignment.
* The fo:flow-source-list formatting object generates no area directly. It is used by the fo:page-sequence formatting object to assign flows to regions.
* The children of the fo:flow-source-list are a sequence of flow-name-specifiers identifying flows of the sequence. These flows must be either all fo:flow formatting objects or all fo:static-content formatting objects. It is an error if they are a mixture.
###### ~~`fo:flow-name-specifier`~~
* The fo:flow-name-specifier is used to specify one flow in a source-list.
* The fo:flow-name-specifier formatting object generates no area directly. It is used by the fo:page-sequence formatting object to assign flows to regions.
* The flow-name-reference property specifies the name of a flow in the source sequence.
##### ~~`fo:flow-target-list`~~
* The `fo:flow-target-list` is used to specify the sequence of regions to which flows are assigned in a particular `fo:flow-assignment`.
* The `fo:flow-target-list` formatting object generates no area directly. It is used by the `fo:page-sequence` formatting object to assign flows to regions.
* The children of the `fo:flow-target-list` are a sequence of `fo:region-name-specifiers` identifying regions in the sequence.
###### ~~`fo:region-name-specifier`~~
* The `fo:region-name-specifier` is used to specify one region in a `target-list`.
* The `fo:region-name-specifier` formatting object generates no area directly. It is used by the `fo:page-sequence` formatting object to assign flows to regions.
* The `region-name-reference` property specifies the name of a region in the target sequence.
