I think the issue is deeper than that, but I asked Girgias we ll see ..

So I rebased still the issue. I wish I was wrong.

The issue was because the example.outputs.85.similar XML entity tried to use the &nspb; HTML entity.

This was clearly shown in the configure output:

[FATAL  1:110] Entity 'nbsp' not defined
[FATAL  1:118] chunk is not well balanced
[FATAL fr/language/predefined/attributes/override.xml 112:33] Entity 'example.outputs.85.similar' failed to parse
[FATAL fr/language/predefined/attributes/override.xml 155:1] chunk is not well balanced

I fixed this with 6baaf9d and updated the docs with 9be2781 to incorporate the markup fixes I submitted in php/doc-en@2c62a67
