This finds the attribute curly braces after an image declaration, extracts
the alt text, and adds it as an attribute to the image, which is useful in
parsing the XML, and will not affect rendering.

Arguments
- images
a nodeset of images
- xpath
an XPath expression that finds the first curly brace immediately
after a node.
- ns
the namespace of the XML

this function assumes that the images entering have a curly brace
following.
