I'm working with a larger amount of equations in a document, written originally in HTML+MathML. The need to have the output in PDF too emerged and I started to use Pandoc to convert the document into md, then to latex, from which pdflatex could make a conventional and professional pdf output. Unfortunately some MathML editors couldn't handle well complicated formulas, and for this reason I embedded latex into html leading to the problem of the less-than and greater-than symbols.
The less-than < (and greater-than >) symbols cannot be used in a html document in a naive way to represent relation between quantities. The following document represents the relation correctly with MathJax (and even by converting to latex with pandoc), but validation by W3C Validator fails the test against HTML.

What workarounds (solutions?) can you suggest to handle this problem?

I substituted all "less-than" < symbols with their named "&lt;" entity inside latex notations. Even though they are not valid latex codes anymore, MathJax represents them correctly, and Pandoc converts them to < correctly too.
