[xsl] Checking for empty elements

Is there a way using XSLT 2.0 to determine whether an element has no
attributes present
in an XML document?

Say, given the type, with default values:

<xs:complexType name="TimeType">
    <xs:attribute name="day" type="xs:unsignedByte" default="0"/>
    <xs:attribute name="hour" type="xs:unsignedByte" default="0"/>
    <xs:attribute name="minute" type="xs:unsignedByte" default="0"/>
    <xs:attribute name="second" type="xs:unsignedByte" default="0"/>

And an element definition of that type:

<xs:element name="time" type="myown:TimeType"/>

Is there an <xsl:if test=... /> to determine the difference between the
empty element (which will have default attribute values if processed)
<time />
and an element with explicit attributes, for example,
<time hour="5" minute="27" />

I'm trying to not process the empty <time /> element.

Thanks, Mike
