Code Inspection: Check Node Test
This inspection checks whether any element/attribute names that are used in XPath-expressions are actually part of an associated XML file or are defined in a referenced schema. This helps to avoid problems caused by typos in XPath-expressions that would otherwise occur when running the script and may even then not be recognized immediately.
<xsl:template match=" h:txtarea " />
If the prefix "h" is bound to the XHTML namespace, the inspection will flag this part of the match-expression as an unknown element name because the correct name of the element is "textarea".
