Hello Steven and co,

Would something like this by okay too:

<bind ref="age" type="integer">
	<alert level=“subtle”><output ref=“longwinded-error-report/en-gb”/></alert>  
	<alert level=“in-your-face”><output ref=“pithy-error-report/en-gb”/></alert>
</bind>

Hint and help too?

Best wishes

Mark

P.S. I’ve had severe depression for a long time, but a change of medication and better support seems to be helping and I’m finding that I am suddenly more interested in the world around me again :)

Still using XForms (XSLTForms) in the wild, probably not very effectively, but hey ho. Here is an example: http://www.aocarchaeologygroup.uk.wizzdns.com/darkAgeScot/


I will try to pay more attention and maybe feel up to joining in again in the coming weeks.
