Subject Re: additional spaces in text - bug or feature
Date Wed, 20 Feb 2002 22:21:48 GMT
Vladislav,

This is happening because the piece of code which writes out the XML
makes a tabbified output which does not play well with
xml:space="preserve".
In effect, it erroneously adds trailing spaces. 

I could argue this is not a bug as the goal is to have accurate
visual rendering and we do have accurate rendering. However, I think
we should fix it anyway. How important is this to you? Is that a 
critical problem?

Note that we are using xml:space preserve in case the string you
draw has leading or trailing spaces which we want to preserve or 
multiple spaces inside the string.

Cheers,
Vincent.
