[xsl] xpath 2 regex

[davep <davep@xxxxxxxxxxxxx>]

	<xsl:template
match="p[matches(normalize-space(), '^[the quick] |
[brown fox]' )]"

I'm having problems interpreting this.
  I think
<p>   the quick .....</p> matches
<p>the quick... </p> matches

what role does the  | take please?
  a simple alternate?

<p>.... brown fox ...</p> Matches?



http://www.w3.org/TR/xmlschema-2/#regexs
seems to show this

...
Doesn't [xxx] indicate a character class?
So what about
<p>.... xof nwbro</p>  Would this match
or basically anything containing any (subset of) of that group of 
characters?

If so, what patter matches a p element which starts with
the string "the quick brown" or contains "brown fox" please?
