what do you mean by "processes only the elements of a particular name space"

do you want any element not in that namespace to generate an error or to
be silently ignored but have its children processed, or something els?

The first case you could do by validating against a suitable schema, or
by having default templates something like
<xsl:template match="*">
  <xsl:message terminate="yes">go away</xsl:message>

<xsl:template match="myns:*">
  default behaviour for myns

<xsl:template match="myns:foo">
  specific behaviour for myns:foo

The second case is XSLT's default behaviour.

the namespace is part of the element name, so you almost always refer to
elements in a particular namespace in xpath (unless using the *

namespaces are an intrinsic part of the model, but the namespace
declarations are just syntax (cf attribute values being part of the
model but choice of " or ' around attribute values is just syntax.
<a xmlns="z"><b></a> and <a xmlns="z"><b  xmlns="z"></a> 
generate identical input trees, just with different surface syntax that
is not observable using xpath, just as the differences between those and
<a xmlns='z'><b></a> and <a xmlns='z'><b  xmlns='z'></a> 
with ' instead of " is not observable.
