Indicates that only metadata should be added to the document and a file should not actually be written to the file system. This is useful for preprocessing documents so they appear in a pipeline with the correct write metadata, while actually writing them later with a second Wyam.Core.Modules.IO.WriteFiles module invocation. Only the following metadata values are written when this flag is turned on: WritePath, RelativeFilePath, RelativeFilePathBase, and RelativeFileDir. The Destination... metadata values are not added to the document when only setting metadata..
