Morpho

The attribute dialogs in Morpho 1.4 allowed a researcher to enter a freetext
'unit' for typing a specific data column for tabular data. Morpho 1.4 seems to
introduce a leading whitespace in the value of the unit tag like:

<unit> ton</unit>

On XSL transformation using $MORPHO_HOME/xsl/eml2attr.xsl, the unit value is
compared to the standard unit dictionary that ships with EML2.0.0. If the
standard unit name is found, a <standardUnit> tag is created with the previous
value. If not, the default is to produce a <customUnit> tag.

Because of the introduced leading whitespace, ' ton' != 'ton', and therefore an
orphaned <customUnit> ton</customUnit> tag is generated, with no reference to
it's STMML unit definition.
