Re: [ANN] XSDBench XML Schema Benchmark 1.0.0 released

It is mentioned in the "Tests" section of the benchmark description[1].
Here is the test outline for that section:

   1. Read XML instance into memory
   2. Create a parser
   3. Load and cache XML Schema in the parser
   4. Start timer
   5. Perform 10000 parse iterations, resetting the parser if necessary
   6. Stop timer
   7. Destroy the parser

It is raw, unparsed text, just read from the file into a memory buffer.

It is probably quite a bit faster than the Pentium 3 1Ghz I was using.
Though the enabled debugging probably slowed down your code quite a bit
as well. But still interesting.
