Wrapper Fails to Load Samples Due to "sequence"

[philn5d-ar]

In all the VAST 4.0 standalone samples there are sequence attributes. However, this is leading to a failure of VAST clients (vast-client from Dailymotion, for example) to fail to parse the sample ad content. We are using Google Ad Manager which delivers a wrapped ad.

In the VAST 4.1 spec:

"3.3.1 Ad Pods and Stand-Alone Ads
TOC Schema
While a single element represents the most common VAST response, multiple ads
may be included as either stand-alone ads or a Pod of ads, or a mix of both. Ads in a Pod
are distinguished by using the sequence attribute for an , denoting which ad plays first,
second, and so on. If the player supports Ad Pods, sequenced ads are played in numerical
order and all ads in the Pod should be played to the best of the player's ability. All sequence
values in a VAST response must be unique."

and...

"allowMultipleAds - a Boolean value that identifies whether multiple ads are allowed in the
requested VAST response. If true, both Pods and stand-alone ads are allowed.
If false, only the first stand-alone Ad (with no sequence values) in the
requested VAST response is allowed. Default value is “false.”"

This means the samples should NOT be allowed in a wrapper, but they are really standalone ads since there is only one. Therefore, the sequence should be removed from each sample with only one ad.
