This isn't actually the best place for questions about the W3C specification, but I'll do my best...

There are clearly omissions from your list, such as xsl:iterate , xsl:merge, and xsl:sort. The list you point to is primarily about parts of the dynamic context other than the context item itself.

I don't think there is any central list of things that change the context item. §5.3.3.1 talks about the principles, but says:

In other cases (for example, where the containing element is xsl:sort, xsl:with-param, or xsl:key), the rules are given in the specification of the containing element.

I think there are one or two cases that are still underspecified in the XSLT 3.0 spec, for example it's not entirely clear what the context is for evaluating xsl:param/@select.

For changing the context node, do these count also?

xsl:copy with @select

xsl:perform-sort

xsl:merge-source

xsl:source-document

You can look for calls of XPathContext.setCurrentIterator()
