Remarks

As mentioned in Source Commands, we can use unknowns-attributes and send more data to data providers like this:

<basis core='dbsource' name='db' run='atclient' source='basiscore' mid='10' lid='1' userid='122504' ownerid='7660' rkey='289979947718473-59625461925771' dmnid='4312'>
   <member name='product-list' type='list' link='/owner_profile.bc' propertyid='8139,8140,87816,87817,87881' order='id desc' perpage='30' pageno='1' />
</basis>

But in some case value is not well-formatted. for example suppose we change above command to send user input to data provider.

<basis core='dbsource' name='db' source='basiscore' user-input='[##cms.form.code##]' >
   <member name='product-list'  />
</basis>

Now if code field of form is:

hi man

Every things is ok, because after data injection, command is:

<basis core='dbsource' name='db' source='basiscore' user-input='hi man' >
   <member name='product-list'  />
</basis>

But if user enter some things like this:

amir's father say: "hi man"

Now after inject data, command is:

<basis core='dbsource' name='db' source='basiscore' user-input='amir's father say: "hi man"' >
   <member name='product-list'  />
</basis>

And this xml is not well-formatted and my be case error in underlying data provider. In this case, we use params tag. So let change command for using param tag:

<basis core='dbsource' name='db' source='basiscore' >
   <params>
      <add name='user-input' value='[##cms.form.code##]'>
   </params>
   <member name='product-list'  />
</basis>

params tag send to data providers in seperated way and so, no error happen in parse command xml.
