阻止函數使用位置參數，除了ValueFromRemainingArguments參數

我目前正在爲Powershell v2.0中的Subversion命令行編寫一個包裝器。我希望能夠遵循命令行儘可能接近的方式。所以，舉例來說，我希望「SVN信息」命令：阻止函數使用位置參數，除了ValueFromRemainingArguments參數

info: Display information about a local or remote item. 
usage: info [TARGET[@REV]...] 

    Print information about each TARGET (default: '.'). 
    TARGET may be either a working-copy path or URL. If specified, REV 
    determines in which revision the target is first looked up. 

Valid options: 
    -r [--revision] ARG  : ARG (some commands also take ARG1:ARG2 range) 
          A revision argument can be one of: 
           NUMBER  revision number 
           '{' DATE '}' revision at start of the date 
           'HEAD'  latest in repository 
           'BASE'  base rev of item's working copy 
           'COMMITTED' last commit at or before BASE 
           'PREV'  revision just before COMMITTED 
    -R [--recursive]   : descend recursively, same as --depth=infinity 
    --depth ARG    : limit operation by depth ARG ('empty', 'files', 
          'immediates', or 'infinity') 
    --targets ARG   : pass contents of file ARG as additional args 
    --incremental   : give output suitable for concatenation 
    --xml     : output in XML 
    --changelist [--cl] ARG : operate only on members of changelist ARG 

Global options: 
    --username ARG   : specify a username ARG 
    --password ARG   : specify a password ARG 
    --no-auth-cache   : do not cache authentication tokens 
    --non-interactive  : do no interactive prompting 
    --trust-server-cert  : accept SSL server certificates from unknown 
          certificate authorities without prompting (but only 
          with '--non-interactive') 
    --config-dir ARG   : read user configuration files from directory ARG 
    --config-option ARG  : set user configuration option in the format: 
           FILE:SECTION:OPTION=[VALUE] 
          For example: 
           servers:global:http-library=serf

...映射到功能如下：

function Svn-Info { 
    param(
     $revision, 
     $depth, 
     $targets, 
     $incremental, 
     $changelist, 
     $username, 
     $password, 
     $no_auth_cache, 
     $non_interactive, 
     $trust_server_cert, 
     $config_dir, 
     $config_option, 
     [Parameter(Mandatory=$false,ValueFromRemainingArguments=$true)] 
     [String[]] 
     $targetsAtRev 
    )

我想這樣稱呼它：

Svn-Info "D:\svn\"@25345 "D:\svn\common\"@35922 -username MyUserName -password MyPassword

不幸的是，它試圖將前兩個參數綁定到$ revision和$ depth（基本上，前兩個參數沒有已經被綁定）。所以基本上，我可以以某種方式停止參數綁定位置的任意數量的參數？

試試這個PARAM東方電氣：

function Svn-Info { 
    [CmdletBinding()] 
    param(
     $revision, 
     $depth, 
     $targets, 
     $incremental, 
     $changelist, 
     $username, 
     $password, 
     $no_auth_cache, 
     $non_interactive, 
     $trust_server_cert, 
     $config_dir, 
     $config_option, 
     [Parameter(Mandatory=$false,ValueFromRemainingArguments=$true, Position=0)] 
     [String[]] 
     $targetsAtRev 
    )
