If I define it as xs:string+ I get the separator and then need to use string-join(). If I drop the as="xs:string" attribute I get the desired result 'abcdef' - but this is because that's the string value of the nodeset. This is very upside down for me. Is it really the case that we will have to be very aware of how many items we are creating and construct large concat()'s, or have a liberal sprinking string-join()'s throughout the stylesheet? Or am I missing something and I shouldn't be using the type xs:string in this way? cheers andrew | |
