Need to understand the differences between advanced function synopsis locations

PowerShell Help

What is the difference between this function where the synopsis is before the function block:

[pre]

<#
.Synopsis
Short description
.DESCRIPTION
Long description
.EXAMPLE
Example of how to use this cmdlet
.EXAMPLE
Another example of how to use this cmdlet
.INPUTS
Inputs to this cmdlet (if any)
.OUTPUTS
Output from this cmdlet (if any)
.NOTES
General notes
.COMPONENT
The component this cmdlet belongs to
.ROLE
The role this cmdlet belongs to
.FUNCTIONALITY
The functionality that best describes this cmdlet
#>

Function Do-SomethingNifty
{
[CmdletBinding(DefaultParameterSetName=‘Parameter Set 1’,
SupportsShouldProcess=$true,
PositionalBinding=$false,
HelpUri = ‘http://www.microsoft.com/’,
ConfirmImpact=‘Medium’)]
[Alias()]
[OutputType([String])]
Param
(

Param1 help description

[Parameter(Mandatory=$true,
ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true,
ValueFromRemainingArguments=$false,
Position=0,
ParameterSetName=‘Parameter Set 1’)]
[ValidateNotNull()]
[ValidateNotNullOrEmpty()]
[ValidateCount(0,5)]
[ValidateSet(“sun”, “moon”, “earth”)]
[Alias(“p1”)]
$Param

)

Begin {}

Process

{

Do-Stuff -Param $Param

}

End {}

}

[/pre]

 

As opposed to this function where it is inside the function block:

[pre]

Function Do-SomethingNifty
{
<#
.Synopsis
Short description
.DESCRIPTION
Long description
.EXAMPLE
Example of how to use this cmdlet
.EXAMPLE

.INPUTS

.OUTPUTS

.NOTES
General notes
.COMPONENT

.ROLE
The role this cmdlet belongs to
.FUNCTIONALITY
The functionality that best describes this cmdlet
#>

[CmdletBinding(DefaultParameterSetName=‘Parameter Set 1’,
SupportsShouldProcess=$true,
PositionalBinding=$false,
HelpUri = ‘http://www.microsoft.com/’,
ConfirmImpact=‘Medium’)]
[Alias()]
[OutputType([String])]
Param
(

Param1 help description

[Parameter(Mandatory=$true,
ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true,
ValueFromRemainingArguments=$false,
Position=0,
ParameterSetName=‘Parameter Set 1’)]
[ValidateNotNull()]
[ValidateNotNullOrEmpty()]
[ValidateCount(0,5)]
[ValidateSet(“sun”, “moon”, “earth”)]
[Alias(“p1”)]
$Param

)

Begin {}

Process

{

Do-Stuff -Param $Param

}

End {}

}

[/pre]

 

Thank you

No difference in terms of how the help is parsed.

However, lots of folks I’ve spoken to recommend keeping help inside the function so that wherever you copy the function, the help comes with it (unless you manually go through and edit it out).
