If the value wasn't defined it's not necessary to append these attributes, right?

Right. Unfortunately I am using xsl:attribute-sets to add the generic sets of attributes that are common to all controls. When using attribute sets XSLT assumes that all attributes should always be added even when no value is specified. This is what the value and title attributes are added with blank values when you specify no value.

Originally I had separate xsl:call-templates for each attribute but this felt very messy and increased code size by many, many lines. Using attribute-sets is the most elegant solution since it is using a powerful feature of the XSLT language. But having the blank attributes is an unfortunate side effect.
