XML.standalone
The XML standalone element defines the existence of an externally-defined DTD. In the message tree it is represented by a syntax element with field type XML.standalone.
The value of the XML standalone element is the value of the
standalone attribute in the XML declaration. It is always a child
of an XML.XmlDecl syntax element. The only valid values for the standalone
element are yes and no. The
following is an example of this:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE s1 PUBLIC "http://www.ibm.com/example.dtd" "example.dtd">
<s1>........</s1>
A value of no indicates that this XML
document is not standalone, and depends on an externally-defined DTD.
A value of yes indicates that the XML document
is self-contained. However, because the current release of IBM® App Connect Enterprise does not resolve externally-defined
DTDs, the setting of standalone is irrelevant, and is ignored.
