[xliff] Reworded paragraph for multiple attribute values in XLIFF

In response to my action item from the
last XLIFF meeting, here is my proposed new version for the paragraphs
in the specification pertaining to attribute values and in particular,
multiple attribute values:

D.2. Attribute Values

Attribute values are case sensitive.
It is strongly recommended that lower-case values are used. The specification
recommends a number of values for some attributes, these are all lower-case.

Where multiple attribute values are
to be used in an XLIFF document, two approaches are used:

        For
enumerated attributes (such as the 'purpose' attribute of <context-group>)
the separator must be a space. 

        For
other textual attributes that are not validated, the specification recommends
the use of the semi-colon as a concatenation separator for values, for
example, multiple contacts may be listed for a <file> with the attribute-value
written thusly: contact-name="Frank Sinatra;Sammy Davis Jnr;Dean Martin".

For reference I have included the current
version of this paragraph below:

D.2. Attribute Values

Attribute values are case sensitive.
It is strongly recommended that lower-case values are used. The specification
recommends a number of values for some attributes, these are all lower-case.

The specification also recommends the
use of the semi-colon as a concatenation separator for values. For example,
multiple contacts may be listed for a <file> with the attribute-value
written thusly: contact-name="Peter;Mark".
