On the Basic tab you can set:
Attribute Scope: It can be a Transaction or Process.
XPath expressions: A table of the XPath expressions and the attributes to map into them.
Namespaces: The namespaces for the document that is to be evaluated.
On the Conditional Execution tab, you can set additional processor execution conditions. Transaction data dependent conditions may be specified here as enhanced expression. If this expression returns anything other than TRUE (ignore case) – this processor will be skipped.
The Deprecated tab allows you to specify the deprecated namespaces that should be processed.
