Re: [xsl] How to store a sequence into an element ... and maintain the sequence inside the element?

I think that, using a schema (for input & output documents) for an XSLT
transformation, in general is very useful. The main benefit is, I think,
stronger type checking of XML input/output data, which reveals many error
early during an XSLT transformation cycle.
