Top-level catalog for tests in the iXML Community Group Test Suite.
Tests have been contributed from several sources, but the core of the test collection are the tests contributed by Steven Pemberton in December 2021.

Grammars 21-40.
Test grammars compiled manually in 2018 and 2019, re-packaged in 2022.
Added test cases where needed and moved to ixml test collection, June 2022.

Grammar for the toy programming language Tosca.
From Susan Stepney, High integrity compilation: a case study. Hemel Hempstead: Prentice Hall International, 1993. Web edition. Tosca is defined in chapter 4; the concrete syntax is specified using Z, not using a grammar, and leaves some things undefined, so the grammar given here is a bit of a reconstruction.

This sample 'squares' program is Stepney's running example. The input string is transcribed from the concrete-syntax version on page 44.
Input string (324 characters)
n : int ; sq : int ; limit : int ;
begin
n := 1 ; sq := 1 ;
input limit ;
output sq ;
while ( n < limit ) do
begin
sq := ( ( sq + 1 ) + ( n + n ) ) ;
n := ( n + 1 ) ;
output sq ;
end ;
end
