A few questions on the SCA proprty values

[Raymond Feng <rfeng@us.ibm.com>]

Hi,

I have a few questions on the SCA property
values.

1. Is a) a valid property definition
in the composite file? If I understand the text in Assembly spec line 991
(As a value, supplied as the content of the property element.), it should
be valid.

a) <property name="prop1"
type="xsd:string">ABC</property>

Please note that prop1 is a string property
and the value "ABC" is the direct text under <property>.
I understand that it can be expressed in two other variants:

b) <property name="prop1"
type="xsd:string" value="ABC"/>
c) <property name="prop1"
type="xsd:string">
        <value>ANC</value>
</property>

3. If the property value is specified
using @file, for example,

<property name="prop1"
file="prop1.txt"/>

How should the content of "prop1.txt"
be used? As the textural inclusion or XML inclusion? Please note if the
"prop1" can have many values (@many="true"), we need
to define multiple instances of the property value in "prop1.txt".
In such cases, the content cannot be a well-formed XML document as there
is no single root element.

Two examples are listed below:

a) Single value:
<value xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200903">ABC</value>

b) Multiple values:
<value xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200903">1</value>
<value xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200903">2</value>

Thanks,
Raymond
