Sequencing, Numbering, and Count

While producing my XML output with XSLT I also need to count the number of nodes I created and add sequence numbers to each node.? Please note that I cannot use the count function on the original document as there is no way to retrieve this data without producing the transformed data first.
?
Eg.? (This is what it looks like now)
?
<ePASS>
        <Document>
??????????? ??????????? <Quote>
??????????????????????? ??????????? <Data>....</Data>
??????????????????????? </Quote>
??????????? </Document>
        <Document>
??????????? ??????????? <Quote>
??????????????????????? ??????????? <Data>....</Data>
??????????????????????? </Quote>
??????????? </Document>
        <Document>
??????????? ??????????? <Quote>
??????????????????????? ??????????? <Data>....</Data>
??????????????????????? </Quote>
??????????? </Document>
</ePASS>
?
This is what needs to look like:
?
<ePASS>
        <Document seq="1">
??????????? ??????????? <Quote>
??????????????????????? ??????????? <Data>....</Data>
??????????????????????? </Quote>
??????????? </Document>
        <Document seq="2">
??????????? ??????????? <Quote>
??????????????????????? ??????????? <Data>....</Data>
??????????????????????? </Quote>
??????????? </Document>
        <Document seq="3">
??????????? ??????????? <Quote>
??????????????????????? ??????????? <Data>....</Data>
??????????????????????? </Quote>
??????????? </Document>
</ePASS>
?
Where the "seq" number is just a counter that is incremented by one.? Plus once the document is produced I need to set the maximum sequence number equal to a variable (In the above example it is 3) so that I can pass this information back to my middleware.
?
