relavant or delete

Hello,

Am I right that the relevant attribute within xforms:bind elements is to affect both the UI and the instance data? Which means that when the relevance for a specific instance element calculates to false, bounded UI elements get inactive and the the instance data is not submitted. 
I would like to make a test before my instance data gets submitted, which prevents <instanceOf> elements within my instance that contain empty xlink:href attributes to get submitted. 
I first thought that I could do that with the relevant attribute, but doing this all UI elements bound to the corresponding instance elements get invisible, too.
So maybe a delete action triggered by a click on the submit button is the answer? That leads me to another question. What should be the correct value for the at attribute in the delete element when I want the delete action to take effect on my whole instance data? (at="//*")?

my instance looks like :

	<xforms:instance>
		<topicMap id="beispiel" xmlns="http://www.topicmaps.org/xtm/1.0/" xmlns:xlink="http://www.w3.org/1999/xlink">
		<topic id="">
			<instanceOf>
				<topicRef xlink:href=""/>
			</instanceOf>
			<baseName>
				<baseNameString></baseNameString>
			</baseName>
			<occurrence>
				<instanceOf>
					<topicRef xlink:href=""/>
				</instanceOf>
				<resourceRef xlink:href=""/>
			</occurrence>
			<occurrence>
				<instanceOf>
     					<topicRef xlink:href=""/>
				</instanceOf>
				<resourceData></resourceData>
			</occurrence>
		</topic>
	...
	</xforms:instance>

how would the delete look like, when I want every <instanceOf> element to not be submitted when the xlink:href attribute of the <topciRef> element is empty?
I tried so much statements, but I wasn't able to make it work the way I want it.
Please help me.

wbr,
Roman

Hi Sebastian and others,

I think this does not solve the complete problem. Namely it would not 
allow the generation of arbitrarily deep UI. One solution for XForms 2.0 
(or 3.0 :)) would be to add a template mechanism, similar to 
xslt:template. This might be quite difficult to implement, though, 
because of the dynamic nature of XForms.
