Following are the relevant definitions from the XPath 2.0 spec.
<quote>
the self axis contains just the context node itself
. is known as, "context item expression".
A context item expression evaluates to the context item, which may be
either a node (as in the expression
fn:doc("bib.xml")/books/book[fn:count(./author)>1]) or an atomic value
(as in the expression (1 to 100)[. mod 5 eq 0]).
The context item is the item currently being processed. An item is
either an atomic value or a node. When the context item is a node, it
can also be referred to as the context node.

I am able to understand this. You could point to sections worth discussing.

An interesting practice I've come across at a client's site is instead
of using . they use self:: instead...
So instead of:
<xsl:apply-templates select="." mode="other"/>
you have
<xsl:apply-templates select="self::elem" mode="other"/>
and instead of:
.//whatever
you have:
self::elem//whatever
While it seemed a little odd to start with, their argument of it helps
locate where you are (especially when . is far away from the match
pattern that's normally used to discover the current node) is
beginning to grow on me...
