[xep-support] rx:pdf-structure-tag=Artifact disabling following graphics rx:alt-description

using XEP 4.21 build 20121114 with oracle jdk1.6.0_27 I am having
trouble using rx:pdf-structure-tag="Artifact" together with
rx:alt-description on different external-graphics within the same region.
eg.

<fo:flow flow-name="xsl-region-body">
   <fo:block>
     <fo:external-graphic src="url(image.png)" rx:alt-description="image1"/>
     <fo:external-graphic src="url(image.png)" rx:pdf-structure-tag="Artifact"/>
     <fo:external-graphic src="url(image.png)" rx:alt-description="image3"/>
   </fo:block>
</fo:flow>

I would expect alt text for the first and third images, but the alt text
doesn't show for image 3. Am I doing this wrong or is there a problem
here? This behavior shows in Reader 9 and Acrobat Pro X.

In other more complex documents I am seeing in some cases (in the pdf)
the alt-text for one external-graphic showing on the next
external-graphic from the fo. I just presented the simple case here.

Thanks.
