The problem here is that the context for the contains(., 'Yes') is not
the same as the context for @outputclass.
Thus the above expression is asking, in effect, "Is there an
@outputclass attribute anywhere (on any kind of element) with a value of
'SupportInfo', and does the current context node (having no relationship
to any aforementioned @outputclass attributes) have a string value
containing 'Yes'?"

What you probably want instead is something like

<xsl:choose>
	<xsl:when test="@outputclass='SupportInfo' and contains(., 'Yes')">

assuming that this code appears inside a for-each or apply-templates
that is selecting p elements.

"//" at the beginning of an XPath expression means "any descendant of
the root of the document containing the context node". If you were
trying to use this to output something for p anywhere in the document,
you'll need to use a for-each or apply-templates select="//p".
