[Zope] Zope modifies HTML order of tags?

It seems to me that Zope is rendering my HTML tag attributs in different order than in the source. For instance I put <table width="100%" cellspacing="2" cellpadding="2"> into property named tabstart. Looking into source produced by Zope, I found <table CELLSPACING=2 CELLPADDING=2 WIDTH="100%" > Why is Zope doing this? Maybe there's good reason, but I'd like to know, because too smart software is sometimes more burden than a help. Also some attributes are omitted in the rendering process. Property "width=106 height=106 border=0 align=right hspace=10 vspace=0" ended up without vspace statement. -- Milos Prudek
