The presence element
This option controls the inclusion of nodes in the XFA Data DOM.
<presence
Properties:
desc="cdata"

...pcdata...
</presence>
The presence element is used within the following other elements:
transform
This option applies only to nodes corresponding to elements with tags that match the value of the
ref
attribute of its enclosing
transform
element.
This option takes effect during the data-load phase. When the content is
ignore
it also causes data from
the XML Data DOM to be blended with data from the XFA Data DOM during the data-unload phase.
For more information about this element see

and

Mapping Rules.
Content
The content must be one of the following:
preserve
The node is included in the XFA Data DOM.
dissolve
The node itself is excluded from the XFA Data DOM but its children are promoted to become
children of the dissolved node's parent.
dissolveStructure
The node itself is included, but its children and their descendents are excluded from the XFA Data
DOM.
ignore
The node is excluded from the XFA Data DOM along with all of its descendents (that is, nodes
corresponding to content of the element to which the node corresponds). However during the
data-unload phase (when writing out a new XML document) the affected content is copied out
from the XML Data DOM into the new document.
remove
The node and is descendents are excluded from the XFA Data DOM and in addition the
corresponding nodes are removed from the XML Data DOM. The result of this is that during the
data-unloading phase a new XML document is produced which lacks the removed data.
The desc property
An attribute to hold human-readable metadata.
