The "as" attribute on xsl:variable is redundant in cases where the value is a literal or a constant subexpression (though it's still good documentation and good software engineering to provide it, like an "assert" expression in Java). It's not redundant in cases like: <xsl:variable name="x" select="document('invoice.xml')" as="document-node(element(invoice))"/> This is saying that you have written your stylesheet on the assumption that the input document is going to be an invoice, and that the system can make use of this information, and that the system will give you an explicit error message if you feed something other than an invoice as input to this stylesheet.
