If you are using Java, then you don't need to use Xalan, you can use Saxon,
which implements the latest standards.

There are broadly two categories of 1.0 processor: open source processors
produced by enthusiastic individuals in their spare time, and open source
processors produced by enthusiastic corporations such as Microsoft and IBM.

The first category didn't get upgraded because the individuals found more
interesting/rewarding things to do with their spare time.

The second category didn't get upgraded because the people within the relevant
corporations who wanted to upgrade them failed to persuade their management
that there was a good business case for spending a couple of million dollars
on software that would be given away free.

So it's basically a failure of the open source "business model". Lots of
people have got value from open source 1.0 processors, and none of this value
has fed back into investment into advancing the technology.

Meanwhile (as I pointed out in my talk on XSLT 3.0 in Prague, which you can
watch on video) there are lots of 2.0 processors available (Saxon, Altova, IBM
Websphere, Intel, Marklogic) but all of them are funded by a commercial
business model, even if in some cases there are free versions available.

The key point is "market". When did you last go to the market and find free
tomatoes on offer?
