I tested My microdata schema.org on google:
The google tools did not return any error...
**Item**
type: http://schema.org/webpage
property:
url: http://127.0.0.1/

**Item 1**
type: http://schema.org/wpheader
property:
url: http://127.0.0.1
headline: website name
image: http://127.0.0.1/design/logo.jpg
description: some text
**Item 2**
type: http://schema.org/sitenavigationelement
You can see I used multiple itemprop="text" for the webpage type...
Is it valid?
If yes you know itemprop="url" for WebPage type is invalid... or itemListElement for ItemList is valid. How can I recognize which itemprop is valid and which one is invalid?
----------------///EDIT///-------------------
<html itemscope itemtype="http://schema.org/webpage">
<body>
<div itemprop="text" itemscope="itemscope" itemtype="http://schema.org/wpheader">
...
</div>
<div itemprop="text" itemscope="itemscope" itemtype="http://schema.org/SiteNavigationElement">
...
</div>
