	How can I set `self`-based input bindings for optional inputs?	为可选输入项设置用到 `self` 变量的输入绑定
	Currently, `cwltool` can't cope with missing optional inputs if their input binding makes use of `self`. Below is an example workaround for this, pending a more sophisticated fix.	目前，如果缺失的可选输入项用到了 `self`, `cwltool` 将无法处理。在更高明的解决办法出现前，下面的例子可作为临时变通一用。
	How can I model a "one-or-the-other" parameter?	构建“非此即彼”参数的模型
	Below is an example showing how to specify different strings to be added to a command line, based on the value given to a Boolean parameter.	以下示例演示的，是根据某个布尔参数的取值，来指定添加到命令行的字符串。
	How do I connect a solo value to an input that expects an array of that type?	将某个元素值与期待该值类型的数组关联起来
	Add a [`MultipleInputFeatureRequirement`](https://www.commonwl.org/v1.0/Workflow.html#MultipleInputFeatureRequirement) along with [`linkMerge: merge_nested`](https://www.commonwl.org/v1.0/Workflow.html#WorkflowStepInput):	将 [`MultipleInputFeatureRequirement`](https://www.commonwl.org/v1.0/Workflow.html#MultipleInputFeatureRequirement) 与 [`linkMerge: merge_nested`](https://www.commonwl.org/v1.0/Workflow.html#WorkflowStepInput) 联合使用
	merge_nested	merge_nested
	The input must be an array consisting of exactly one entry for each input link. If "merge_nested" is specified with a single link, the value from the link must be wrapped in a single-item list.	输入必须是一个数组，每个输入链接只包含一个条目。如果使用单个链接指定“merge_nested”，则链接中的值必须包含在单项列表中。
	Which means "create a list with exactly these sources as elements".	这段话意思是，“创建一个列表，其中的元素正是这些源”
	Or in other words: if the destination is of type `File[]` (an array of `File`s) and the source is a single `File` then add `MultipleInputFeatureRequirement` to the Workflow level `requirements` and add `linkMerge: merge_nested` under the appropriate `in` entry of the destination step.	换言之：如果目标的类型是 `File[]`（元素类型为 `File ` 的数组），而源是单独一个 `File`，那么将 `MultipleInputFeatureRequirements` 添加到工作流级别的 `requirements`，并在目标步骤相应的 `in` 条目下添加 `linkMerge： merge_nested`。
	How do make an input optional? 💯
