self-referencing elements in XML
I came across some self-referencing elements in xCBL3.0 (one of the example is below). Is it legal to have self-referencing elements in XML ? I am having a major problem while I try to create a data structure using WebMethods using this DTD.... PackageReference (Element) (Namespace: XCBL30) Content: Quantity? , PackageIDReference (Type: int) , PackageReference? Description: The PackageReference element provides a reference for the packaging of the item. Quantity is the quantity of the item in the referenced package. PackageIDReference references the package ID of the package containing the item found in the PackageDetail element. PackageReference provides a reference for the packaging of the item. Any comments ? Thanks Anshul
