XPath spec, 2.3:
Every axis has a principal node type. If an axis can contain elements,
then the principal node type is element; otherwise, it is the type of
the nodes that the axis can contain. Thus,
* For the attribute axis, the principal node type is attribute.
* For the namespace axis, the principal node type is namespace.
* For other axes, the principal node type is element.
---
So, preceding-sibling::* will select the preceding sibling of the
type 'element', as I read it.
Am I misinterpreting the spec?
