XSLT: How to write "Yes" if element/attribute exist or "no" if not?

[Mark Richards]

The solutions for the following problems seems to be simple but I did not found a (convenient) solution:
Assume we have a number of elements of the same type under a common parent e.g.


<person ... myattr="aaa">Paul</person>
<person ... myattr="bbb">Peter</person>
<person ... myattr="ccc">Karl</person>
.....
<person ... myattr="ddd">Stan</person>


Now I want to write a text from inside an XSLT script with the following conditions:

1.) Write "yesccc" (e.g. into file) if an element <person> with an attribute value myattr="ccc" exist
otherwise write "noccc"

2.) Write "yesMick" (e.g. into file) if an element <person> with a value <person ...>Mick</person> exist
otherwise write "noMick"

2.) Write "yesAttrib" (e.g. into file) if an element <person> have an attrib myattrib="....." defined
(value unimportant) otherwise write "noAttrib"

Thank you for your help

<xsl:choose>
<xsl:when test="//person[@myattr = 'ccc']">
<xsl:text>yesccc</xsl:text>
</xsl:choose>
<xsltherwise>
<xsl:text>noccc</xsl:text>
</xsltherwise>
</xsl:choose>
