LaTeX ? MathML

• TeX4ht
• Mainly good results
• Some problems
• open intervals denoted as a,b
• equation groups
• prime

nb ? MathML

• Mainly good results
• Some problems
• some characters are coded into Private Use Area
  block
• mathsize attribute is given without unit
• all outputs are encoded as MathML, for example

mws ? MathML

• Adequate results
• Some problems
• use of images instead of MathML
  
• D5 produces erroneous MathML
• lot of differences in presentation
