Whatever the technical background is, saying this comes through as arrogance to the users, since (almost?) nothing but XXE renders it like that.

Surely nobody can sue you even if you display pink hippos instead of those white-space, it's your basic freedom right... but you still shouldn't do that. > Daniel Dekany wrote: >> Here is the problematic example (from the attached >> ws-between-blocks-test-fails.html): >> >> ... >> <body> >> <div> >> <p>Para 1</p> >> <p>Para 2</p> >> <p>Para 3</p> >> </div> >> </body> >> ... >> >> At least with the default XHTML CSS, between each p element a text >> node will be displayed that contains a space (visually a space).
