Thanks for providing the test case.
The limit for a TinyTree is 1024 namespace prefixes used in a single document. We increased the limit in Saxon 9.8, it was previously 1024 prefixes globally.
The limit is there for a good reason and I don't propose to change it. But I'll look at whether we can produce better diagnostics when the limit is exceeded.
There used to be an application (Apache Axis?) that generated XML documents with a ludicrous number of namespace bindings, but I haven't seen the problem for many years. It would be interesting to know whether this is a real requirement.

- Applies to branch deleted (
9.9)
- Fix Committed on Branch 10, 11, trunk added
- Platforms .NET, Java added
The limit is actually 2047 namespace prefixes per document.
I've patched it to fail with a slightly more informative exception.
Thanks for the prompt resolution.
It is aligned with your expectations.
There is no justifiable requirement for using so many (thousands) of namespace bindings.
Applications that do this should be redesigned.
If ever there is a justifiable requirements for this, I will inform you.
The focus here is more to improve the error, indeed, so that it is more informative.
Thanks again for addressing this so promptly.
