MathML does have an entity of that name but always in XML if you use a
named entity other than the five predefined ones (apos amp quot lt gt)
you need to reference a DTD that defines the entities.
So in this case you need something like
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN"
"http://www.w3.org/Math/DTD/mathml2/xhtml-math11-f.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
....
Without that, the file is not well formed XML and so will generate an XML
error in any XML parser before the MathML system really sees the file at
all.
An alternative to referencing the DTDs to reference the character by
number rather than by name, so ∫ in this case.
Appendix A of the MathML spec has some more suggestions regarding DTD
usage.
