I think maintainability should sell by itself, by virtue of cost savings
for bug fixes, changes, or new features. Maybe a future XSLT2 solution
won't live up to the promises of XY% performance gain, so I think you
shouldn't even try to sell on this argument but rather try to direct
their attention towards cost savings by maintainability. Of course you
should try to quantify the possible savings. Take, for example, the last
10 change requests and their outcome in terms of man-hours spent and
bugs newly induced. Or the quota of rejected change requests due to
estimated costs or lack of predictability. Then quote the experts --
Andrew, Dr Kay, etc. -- saying something like "XSLT2 increases
maintainability by YZ%, lowering maintenance costs by the same amount".
Of course management will object that these gains are only achievable if
the people in charge of maintaining the solution are experiences XSLT2
developers. So you have to offset training costs from the prospective
gains. And maybe you'll have to hire an expert for some days (depending
on complexity) to help you redesign the application.
For immediate performance gains, you should use a profiler (will saxon -TP cope with XSLT1 stylesheets? it should) and then consider using xsl:key or other adequate measures on the bottlenecks. But these are rather speculative or general thoughts, given that the only time I spent at Tesco's was when I bought something there in England or Prague.
