RE: get/set methods for element

[Wolfgang Hoschek <wh...@lbl.gov>]

Hi, just my 5 cents on the issue at hand.

Although xsd:any with maxOccurs can be manipulated with XMLCursor this 
seems an unnecessary complication to me.
IMHO, xmlbeans should ALSO spit out the highly convenient array accessor 
methods it usually spits out when using concrete elements instead of 
xsd:any, as follows:

getAnyArray()
getAnyArray(int)
insertAny(int, XMLObject)
removeAny(int)
setAnyArray(XMLObject[])
setAnyArray(int, XMLObject)
sizeOfAnyArray()

This would mean that things like the example below (which i use in a 
great many actual schemas) can be manipulated "as expected" and with a 
minimal learning curve.

<xsd:complexType name="ItemSetType">
	<xsd:sequence>
		<xsd:any processContents="lax" minOccurs="0" maxOccurs="unbounded">
	</xsd:sequence>
</xsd:complexType>

Am I missing out on something here?
