Processing starts at the root node of the source tree. The best matching
template for that node is found and instantiated. The end.

Any template might contain an xsl:apply-templates or xsl:for-each instruction
that directs the processor to select more nodes for processing. In the case of
xsl:apply-templates, the best matching template for each of those nodes is
found and instantiated. In the case of xsl:for-each, the best matching 
template is considered to be in the content of the xsl:for-each element.

So you control the processing order via the use of xsl:apply-templates and
xsl:for-each instructions. The match attribute of a template merely declares
that this template matches nodes of a certain pattern.

There are built-in templates for each type of node, if you don't override them 
with your own.
