* pname:commandBuffer must: have been created with a pname:level of ename:VK_COMMAND_BUFFER_LEVEL_PRIMARY
* Any given element of pname:pCommandBuffers must: have been created with a pname:level of ename:VK_COMMAND_BUFFER_LEVEL_SECONDARY
* Any given element of pname:pCommandBuffers mustnot: be already pending execution in pname:commandBuffer, or appear twice in pname:pCommandBuffers, unless it was created with the ename:VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT flag
* Any given element of pname:pCommandBuffers mustnot: be already pending execution in any other sname:VkCommandBuffer, unless it was created with the ename:VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT flag
* Any given element of pname:pCommandBuffers must: be in the executable state
* If fname:vkCmdExecuteCommands is being called within a render pass instance, that render pass instance must: have been begun with the pname:contents parameter of fname:vkCmdBeginRenderPass set to ename:VK_SUBPASS_CONTENTS_SECONDARY_COMMAND_BUFFERS
* If fname:vkCmdExecuteCommands is being called within a render pass instance, any given element of pname:pCommandBuffers must: have been recorded with the ename:VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT
