The magic of AVT's ? Am I right in summarising that an Attribute Value Template is: (in very simple English) An expression inside curly brackets {} It can only be used when adding an attribute to an element which is to go into the output tree? And nowhere else? E.g. <xsl:tempalte match ="x"> <elem attrib="{some-value}"> etc. some-value can be an xpath expression such as path/to/sought/element or a variable. As Mike says, we can't use it in <xsl:template match=" ..... "> we can't use it in <xsl:value-of select=" ...."> we can't use it in <xsl:variable select="....."> Am I nearly there?
