Yes, '1A' will always be "less than" '20' when compared as strings. String sorting is based on the numeric value (usually ASCII) of each successive character. Thus '10000000' will be "less than" '2'.

I've recently taken over an app that I didn't develop.

I found this in the code:

<xsl:if test="/Output/response/Field < '20'">

This is confusing to me for a few reasons.  

1) The '20' is in quotes
2) the value of the Field node is most often a number, but on some occasions it's a letter/number pair, like 1A or 1B.

Can this check ever work?  Would 1A ever be "less" than '20'?
