Additional context

[joshgoebel]

The definition of variable likely needs to be tightened up:

highlight.js/src/languages/gherkin.js

Lines 34 to 36 in fd30701

	className: 'variable',
	begin: '<',
	end: '>'

What are the exact syntax requirements for variables in Gherkin?

from https://cucumber.io/docs/gherkin/reference/#step-arguments

Scenario outlines allow us to more concisely express these scenarios through the use of a template with < >-delimited parameters

There are no accurate definition of step parameter, i think we can at least assume the < and > must be in the same line, and there aren't any '<' and '>' between the <>
