	// Required indicates whether the practitioner must enter a value for
	// this attribute or not. Required and Optional cannot both be true,
	// and Required and Computed cannot both be true.
	Required bool

	// Optional indicates whether the practitioner can choose to enter a value
	// for this attribute or not. Optional and Required cannot both be true.
	Optional bool

	// Computed indicates whether the provider may return its own value for
	// this Attribute or not. Required and Computed cannot both be true. If
	// Required and Optional are both false, Computed must be true, and the
	// attribute will be considered "read only" for the practitioner, with
	// only the provider able to set its value.
	Computed bool

	// Sensitive indicates whether the value of this attribute should be
	// considered sensitive data. Setting it to true will obscure the value
	// in CLI output. Sensitive does not impact how values are stored, and
	// practitioners are encouraged to store their state as if the entire
	// file is sensitive.
	Sensitive bool

	// Description is used in various tooling, like the language server, to
	// give practitioners more information about what this attribute is,
	// what it's for, and how it should be used. It should be written as
	// plain text, with no special formatting.
	Description string

	// MarkdownDescription is used in various tooling, like the

	// about what this attribute is, what it's for, and how it should be
	// used. It should be formatted using Markdown.
	MarkdownDescription string

	// DeprecationMessage defines warning diagnostic details to display when
	// practitioner configurations use this Attribute. The warning diagnostic
	// summary is automatically set to "Attribute Deprecated" along with
	// configuration source file and line information.
	//
	// Set this field to a practitioner actionable message such as:
	//
	//  - "Configure other_attribute instead. This attribute will be removed
	//    in the next major version of the provider."
	//  - "Remove this attribute's configuration as it no longer is used and
	//    the attribute will be removed in the next major version of the
	//    provider."
	//
	// In Terraform 1.2.7 and later, this warning diagnostic is displayed any
	// time a practitioner attempts to configure a value for this attribute and
	// certain scenarios where this attribute is referenced.
	//
	// In Terraform 1.2.6 and earlier, this warning diagnostic is only
	// displayed when the Attribute is Required or Optional, and if the
	// practitioner configuration sets the value to a known or unknown value
	// (which may eventually be null). It has no effect when the Attribute is
	// Computed-only (read-only; not Required or Optional).
	//
	// Across any Terraform version, there are no warnings raised for
	// practitioner configuration values set directly to null, as there is no
	// way for the framework to differentiate between an unset and null
	// configuration due to how Terraform sends configuration information
	// across the protocol.
	//
