ISwDMApplication.CopyDocument Method - details about children array parameter

Trying to copy some documents using the Document Manager API. From the help there is the following documentation:

Parameters

fromName
Full path and filename of the document to copy
toName
Full path and filename of the document to which to copy fromName
fromChildren
Array containing the full path and filenames of the child documents dependent on the document specified for fromName
toChildren
Array containing the new full path and filenames of the child documents to which to copy the child documents specified for fromChildr
option
Copy options as defined by SwDmCopyOptions
pSrcOption
Pointer to an ISwDMSearchOption object

What would child documents be defined as? Components? External references? Assemblies that use the document that I am

moving?

A bit more background...I will be moving documents that exist outside my PDM vault into the PDM vault.

Any help would be appreciated.
