Hello,

In XForms, "instance data" exists in a special data structure called the
"XPath Data Model", which is defined, not surprisingly, in the XPath 1.0
specification. This gets initialized from the XML inline or linked from the
<xforms:instance> element.

Instance data is separate from the containing document, and can't be
accessed through normal means (such as
window.document.getElementsByTagName(), etc.), only through XPath
expressions.

Thanks,

.micah

P.S. The Working Group is finalizing a way for script to get access to the
instance data, though this won't work through window.document....)

point to the
proper part of the instance data

how should this instance data be used?
