# The [document highlight](https://microsoft.github.io/language-server-protocol/specification#textDocument_documentHighlight)
# informs the editor all relevant elements of the currently pointed item for highlighting. For example, when
# the cursor is on the `F` of the constant `FOO`, the editor should identify other occurrences of `FOO`
# and highlight them.
#
# For writable elements like constants or variables, their read/write occurrences should be highlighted differently.
# This is achieved by sending different "kind" attributes to the editor (2 for read and 3 for write).
