File Doc/library/xml.etree.elementtree.rst (right):

https://bugs.python.org/review/28235/diff/18636/Doc/library/xml.etree.elementtree.rst#newcode491
Doc/library/xml.etree.elementtree.rst:491: is a string containing XML
data.  *parser* is an optional parser instance.
Would be nice to start sentences with capital letters. I suggest either
*Parser* or something like “The *parser* argument is . . .”
