In spatialReference.xsd and spatialRaster.xsd the use of units is inconsistent.
eml-spatialReference.xsd defines 2 types which are lists of units, very similar
to what is going on in the attribute and coverage schemas (see bug #1019
comment #4). 

<simpleType name="lengthUnits"> and
<simpleType name="angleUnit">
each of which is an enumeration that includes a group units which are also in
standardUnits, but as implied by the names, their lists are units of type
length and angle, respectively.  The types are used inconsistently:
eml-spatialReference.xsd:2215:    <xs:element name="altitudeDistanceUnits"
type="xs:string">
eml-spatialReference.xsd:2273:    <xs:element name="depthDistanceUnits"
type="xs:string">
eml-spatialReference.xsd:2386:    <xs:element name="unit">
eml-spatialReference.xsd:2396:    <xs:attribute name="name" type="angleUnits"
use="required">
eml-spatialReference.xsd:2499:    <xs:element name="unit">
eml-spatialReference.xsd:2508:    <xs:attribute name="name" type="lengthUnits"
use="required">
eml-spatialRaster.xsd 793:      <xs:element name="waveLengthUnits"
type="spref:lengthUnits" minOccurs="0">
