  "  <time_range>0 1</time_range>",
  "</OpenSimDocument>"
), tpl)

out <- tempfile(fileext = ".xml")
result <- opensimWriteToolSetupFromTemplate(
  template_file = tpl,
  output_file = out,
  fields = list(model_file = "my_model.osim", time_range = "0.5 2.0")
)
result$applied_tags
#> [1] "model_file" "time_range"
readLines(result$output_file)

#> [2] "  <model_file>my_model.osim</model_file>"
